Six Ways to Sunday: Supreme Six-millimeter Cartridges

September 25, 2025blog.243 win, 6mm, 6mm ARC, 6mm creedmoor, 6mm GT, six millimetercoldboremiracle

Preface

Six-millimeter cartridges are very popular for various shooting activities. Their low recoil and high velocity mingled with great ballistic performance make them optimal for many purposes. Today I intend to take a walk through a selection of popular six-millimeter cartridges and why you might want one over the others. Whether you find yourself considering a six-millimeter for your next purchase, or trying to diversify your 6mm collection I hope we might be of help.

.243win, 6mm Creedmoor, 6mm GT, 6mm ARC, six millimeter, cartridge — **Hornady** is a big supporter of the six millimeter family

Old School

If you grew up in the 60’s and 70’s you were likely to run into a .243 Winchester on a typical deer hunt. A derivative of the always popular 308 Winchester; the .243 has always been a popular low recoiling hunting cartridge. Launched about the same time from a competitor, the 6mm Remington was a less popular but comparable option. Both of these cartridges have stood the test of time, pushing their typical 70-100 grain bullet quite fast. Making them great for varmint hunting and smaller big game animals.

There quite a few old **Winchester Rifles** out there in .243

The characteristics of these cartridges often led to them being relegated to either a “ladies caliber” or something for new shooters. There is surely nothing wrong with that, but they certainly shouldn’t be looked at as a lesser cartridge. I would happily take a .243 on a deer hunt or something comparable, the lightning speed and flat trajectory would come in very handy.

Way back then, you could have purchased a Model 70 chambered in .243. These days there are rifles from nearly every manufacturer chambered in the cartridge. Whether you want a bolt-action rifle from Savage or Sako, or even a lever-action .243 from manufacturers like Henry.

Modern Performers

If the .243 Winchester was such a good thing, and is still a popular chambering in todays modern firearms, you might ask why fix what isn’t broken? Hornady released the 6mm Creedmoor nearly ten years ago, much to the horror of the Creedmoor haters it took off. With a supply of high quality components it made sense. But what did the 6 Creedmoor have that the .243 didn’t already cover you might ask? Modern performance is the answer, Creedmoor’s came with aggressive twist rates like 1:8 and 1:7.5. The .243 has a slower twist rate which limits its ability to stabilize many modern bullets larger than 100 grains. The faster twist allowed the 6 Creedmoor to push bigger bullets like 108’s and 115’s at fantastic speeds, giving it a huge ballistic advantage.

Competition rifles like this **6mm Creedmoor Browning X-Bolt** have all the modern features

One of my favorite 6mm cartridges is the 6mm GT. After the success of cartridges like the 6mm Creedmoor and competition cartridges like the 6 Dasher and 6 XC, the 6mm GT was released by GA precision and produced by Hornady. Finding a happy medium of performance and longevity, the 6GT fits easily into AICS magazines like the others I just mentioned. It does this while giving excellent ballistic performance and better barrel life than larger cartridges.

All of these modern performers are shorter cartridges than the older .243 Winchester, which allows them to load longer higher ballistic coefficient bullets and feed from magazines. And the smaller powder charges allow longer durability before the chamber throat is eroded causing degraded accuracy.

Modern Sporting Rifles

Any of the cartridges mentioned today could be and frequently are chambered for semi-automatic rifles like the popular AR pattern. I would be remiss if I didn’t mention the very popular 6mm ARC, as it is the most likely to fit into this category. For a variety of reasons, but mainly because it fits in a 5.56 sized action and magazine. The 6 ARC offers 6mm attributes like ballistic performance and heavier bullets while still fitting into the average AR15 rifle.

(Top) my Desert Tech MDRX with its own custom 6 ARC barrel, and a Primary Arms GLx scope and **YHM Turbo suppressor**

Additionally due to its smaller size, it burns far less powder extending the accuracy life of the barrel. This makes even more sense in a semi-auto as they tend to shoot much higher round counts than typical bolt-action rifles. There are a great variety of 6 ARC autoloading rifles available like the CMMG Resolute series of rifles.

the Howa Mini has been a fantastic little hunting rifle for the whole family

The 6 ARC can obviously be used in bolt-action rifles as well, where it does an excellent job. Additionally the 6 ARC is also typically given a 1:7.5 twist which helps it handle modern bullet selections. I am a bit partial to the Howa Mini, a rifle we have used with great success. But there are also great bolt-action options from Ruger and Savage Arms. With the cartridge gaining in popularity every day, you are likely to find six of one, and half a dozen of another.

Nightstick TWM-30-T Weaponlight

September 9, 2025Ancillary gear, Product reviewnightstick, pistol, pistol light, twm-30-T, weapon light, x300coldboremiracle

Introduction

I love a good pistol and light combination, especially matched with a good red dot. Such being the case I am always looking for additional light options. Several of my full size pistols use the popular SF X300, but when I spotted today’s subject I expected it would drop right in place of the X300. Today we are looking at another weapon light from Nightstick, this one is the Nightstick TWM-30-T weaponlight for handguns.

Nightstick weaponlight, Nightstick, TWM-30-T, pistol, shadow systems, dr920,

The TWM-30-T has a very similar presentation, with two CR123 batteries side by side. Mounted by a picatinny clamp to the accessory rail of most handguns, it comes with multiple spaced anchor plates to adjust where the light rides on the pistol. Adding features to the controls also gives the Nightstick unit a leg up over competitors.

In the Box

When you receive the Nightstick TWM-30-T, everything you need is in the box. There are batteries, tools, and a couple mounting solutions to customize how it rides on your pistol. An owners manual also comes tucked in so you can read up on it.

Nightstick weaponlight, Nightstick, TWM-30-T, pistol,

I really appreciated the fasteners that hold everything in place. Part of me dislikes having life saving equipment “snap on” or snap closed for example. I like that the battery compartment is secured by a screw, as is the the picatinny anchor. The light comes with four different options that you can change out to see where the light best fits on your pic-rail. I found it very convenient to remove the screw and just sit the various anchor plates in place until one of them lines up where you want it.

Programming Controls

The controls of this light are very handy, and easy to remember and understand. I found them to be way ahead of the competition I mentioned earlier. Most lights have a temporary illumination option as well as a full-on setting. The Nightstick TWM-30-T control module gives those settings and more.

Using both buttons in unison, you can press and hold to code in functions like a complete lockout to conserve battery. Or you can engage a strobe feature allowing the user to have a steady beam on command, or a strobe function to blind an opponent.

Nightstick weaponlight, Nightstick, TWM-30-T, pistol, surefire, x300t, — As you can see, the TWM-30-T is a touch shorter than the X-300 Turbo

Perhaps my favorite function is the temporary-on feature. If you push and hold either button, the light will stay on until you release it. Whereas if you simply push and release either button the light stays on. Once you’ve figured our all the functions its very easy to cycle through the functions and get the performance you want.

Compatibility

I found it was very easy to fit the TWM-30-T to a variety of handguns, using the different anchor plate wasn’t always necessary but it was helpful now and then. It seemed perfectly compatible with all my Glock clones, as well as my X5 Legion P320, as well as my Staccato XC.

Nightstick weaponlight, Nightstick, TWM-30-T, pistol, glock, ruger, rxm, staccato XC, shadow systems dr920, sig sauer, p320 X5, Legion, — Here you can see how the Nightstick fit on several popular pistols (clockwise from top left) the **Shadow Systems** DR920, the **Staccato XC**, the **Sig Sauer P320 X5 Legion**, and the Ruger RXM

Aside from fitting all the pistols (which was expected) the TWM-30-T also fit easily into all of my holsters. This was an incredibly welcome convenience, as I love my holsters. The Nightstick is also a little more compact than other popular competitor’s lights, which might be helpful in some scenarios.

Shooting in the Dark

Thankfully I don’t need to shoot in the dark often, but it’s always something to be prepared for. More than anything I spent a lot of time shooting at dusk as the sun went down. To see how the controls functioned in real time while drawing my pistols.

Nightstick weaponlight, Nightstick, TWM-30-T, pistol, surefire, x300, turbo, — for comparison, here are the two beams seen at approximately 15-yards

In the interest of comparison, I did put the beam of the TWM-30-T against others to see how it looks at night time in pure darkness. The 900 lumens of the Nightstick looked great in the darkness.

Pros and Cons

In favor of the Nightstick TWM-30-T, there is much to say. Being able to order it directly off of Amazon for the price of $139 is almost reason enough in my opinion to get one. The fantastic programmable control makes it a smarter choice than some others. And the final blow that would make this a slam dunk is its compatibility with so many guns and holsters. With so many great things going for it, the fact that it is produced in Texas by Americans is simply icing on the cake. (Edit: it would seem they are manufactured overseas for the Texas based company)

I really couldn’t come up with something about this light that was bad. It mounts better than many others, its controls are better and can all be done with a single finger. I guess the only thing that would make it better would be to incorporate a laser without changing the external dimensions. But I guess I’m reaching there.

Nightstick weaponlight, Nightstick, TWM-30-T, pistol, Vortex defender XL, sig sauer, p320, x5, legion, — the Nightstick made a perfect companion to the X5 with it’s **Vortex Defender XL**

Conclusion

I was very happy to find another weapon light with such great compatibility. Something I could use across various pistol and holster combination. Even more pleasing was finding how much I liked about this light in particular. Whether you are simply looking for a light for your CCW, or something for a duty pistol this is a great option. I suppose if the National Tactical Officer Association endorses and recommends these lights, they are good enough for me. If you also fall in that category with me, then give one of these a try. You can order the Nightstick TWM-30-T right here and have it shipped right to your door.

Winchester Supreme Optics 10×50 Binoculars

September 8, 2025Optics, Product review10x50, binoculars, binos, winchester, winchester supreme opticscoldboremiracle

Preface

In another time of my life, it seemed popular for big outdoor names to offer everything from knives to cufflinks. Even as a child I figured out that some of these items were just rebranded Chinese junk. It seems many of the mighty have fallen these days, and their names sold time and again. Our subject today is the Winchester Supreme Optics 10×50 Binoculars, a competitively priced and quality built binocular. If your’e not sure what that has to do with my intro, let me clarify.

Sadly, the great Winchester name lost its place some time ago. The name suffered various changes of hands and its product lines were sold to different interests. Having once been a dominant firearms company, I was very sad to see this happen over the course of my life. But, Americans are good at comebacks…

Winchester Supreme Optics

Winchester Supreme Optics looks to bring back the quality and standard of the Winchester name. Our first look at these binoculars proved to impress me, so I am looking forward to seeing how the rest of their products perform.

Besides the binoculars tested here today, Winchester Supreme Optics also makes other binocular models as well as several rifle scopes, thermal optics as well as spotting scopes. I can assure you based on the binos in-hand, these are not some rebranded trash. It seems the new management at Winchester Supreme Optics has their eye on higher quality and more modern products.

Supreme 10×50 Binoculars

These Supreme binoculars are built on a robust thermoplastic body, with fully coated lenses and tactile grip exterior. The HD glass makes for sharp viewing with edge to edge clarity and brightening low-light images. The internal silver coated prism transmit light better and add contrast to the image. Of course it is nitrogen filled to prevent fogging and sealed to be impervious to the elements.

It also has the standard things you’d expect; tripod mounting lug, lens covers, lens cloth, sling attachments etc. It comes with a padded case and the typical padded sling to hang from your neck. As you might expect like with most binoculars, the sling and case would be set aside in favor of something more comfortable.

Fielding the Winchester Supreme Binoculars

Immediately after receiving the 10×50 binoculars, I went outside to begin evaluating them. I was greeted with a bright image, with clean edges and great contrast. Me and the boys in the office spend every fall hunting in these Rocky Mountains, all took turns looking around the neighborhood. My very first impression was very good, and the others also offered a positive impression.

One of my pet peeves about binoculars is the need to focus each individual barrel of the bino. I understand it is normal especially since not everyone’s eyes are the same. However I found that with these Supreme 10×50’s we spent very little time adjusting between users. It seemed as though the sweet spot focal-length was far more forgiving than other binoculars I’ve used. Even models that cost four or five times more than these.

Into the Mountains

With fall upon us, we took the Winchester Supreme binoculars into the mountains to do our typical scouting trips for mule deer and elk. The clean air at 9,000 feet looked spectacular through these binoculars. We glassed for hours inspecting every thicket and rock formation. I was impressed with how well these binoculars gave sharp focus at any realistic range.

Even in the early predawn light, I found the contrast of these binoculars to be great. Like those moments right at shooting light where you need to identify a shooter versus a non-shooter. The large 50mm objective does well at compressing the available light into a clean image with good depth. This allows you to properly identify your quarry.

Desert Heat

As summer nears its close, my son and I spent some time in the dry desert of the Great Basin. We would soon be chasing Pronghorn Antelope out here, and using the Supreme binoculars to inspect potential bucks would come in handy.

The yellowing landscape makes it feel warmer than it really is, and there is plenty of mirage to perceive. Again, the clear contrast of these binoculars made it an excellent tool as we scoured the desert looking for antelope.

Pros and Cons

I’ll start out with the positive aspects of these binoculars. First off I must say that for the price these are a great deal. Sub $200 binoculars are often trash-tier, like something you’d give your sticky fingered nephew for his birthday. I must say that for the $219 price of these binoculars they are fantastic. They also look sharp, avoiding the often cheesy look of lower priced products. The binos fit perfectly in both of my binocular harness’.

I already mentioned how I really like the ease of which they are focused, and the adjustable eye-cups make it quick to customize for each user. The optical performance is for sure the star of the show. Had I not been able to see the binoculars prior to looking through them, I would have expected them to cost double or more.

If I had to give these binoculars a demerit, it could only be their foreign manufacture. It’s a painful line to walk between inexpensive great products built overseas and more expensive ones made here at home. I must say, despite foreign manufacturing, they have upped their game significantly.

Final Thoughts

I have been very impressed with these Winchester Supreme Optics 10×50 binoculars over the last few weeks of glassing. And I would not have expected to so pleased with a pair of binoculars priced at only $219. My family and I look forward to putting these to some hard use during this hunting season. And I am pleased to see the Winchester name get back where it belongs, bringing quality products to American outdoorsmen. Stay tuned for more, as this wont be the last we hear of Winchester Supreme.

Gritr Gear Tactical Range Bag

Introduction

We all love little items that make our hobby easier to practice, and today I am bringing you another one. Gritr Gear makes a variety of shooting accessories that are both affordable and high quality. Today I am sharing my experience with Gritr Gear’s Tactical Range Bag, a sure way to better organize and transport your shooting accessories. The Tactical range bag has a variety of features that will help you keep your range gear clean and organized with durable construction built to last.

gritr gear, gritr tactical range bag, range bag,

Construction

Gritr Gear’s range bag is made from 500D nylon material that is durable and light. The bag is stitched and reinforced where it counts and uses heavy duty dual zippers for closure. Aside from the exterior of the bag, the interior uses various materials to optimise its use. The pouches are lined with a soft fleece like material to protect your pistols and other accessories from scratches.

Apart from the various pouches and pockets for organizing your stuff, the bag also features various Molle panels within to allow you to add or change the internal design. I was very pleased to find a removable hard panel that you can either use or remove to add strength and rigidity to the main bag compartment.

Bag in a Bag?

The Tactical Range Bag also features various sub-assemblies. you will find inside the main compartment a smaller tote that can be used to carry and quickly remove everything from the main compartment. The inner tote has two zippered pockets on each side, again lined with fleece to protect your gear. Zippers use reinforced pull-tethers making it easy to use with gloves.

And if that wasn’t enough, there is also an even smaller bag within, like a set of nesting dolls. The smaller bag is lined inside with pockets and a zippered mesh pouch. One could use it as a tool pouch or safety gear like hearing protection and such, though it is labeled as a QD IFAK.

gritr gear, gritr tactical range bag, range bag, IFAK — the interior of the IFAK pouch

Aside from the diverse pocket offerings, there is an impressive amount of velcro surfaces on nearly every side of the bags. This comes in handy for folks who love to spice up their presentation with patches and logos.

Exterior

The bag is available in various colors, I chose M81 Woodland camo for obvious reasons. Other colors like black, FDE, Green as well as a retro 80’s pastel on black pattern in case you want to make a statement.

Covering the top of the main compartment is a large velcro lined dual zipper lid. Strong zippers slide easily making it quick to open and close the bag sigle-handedly.

Carrying the bag is easy using the large nylon loop carrying handles, or you can use the large padded shoulder strap that clips onto each end. Gritr even went as far putting hard rubber feet on the bottom of the bag, to prevent the bottom of the bag from wearing out. This would come in handy riding in the bed of my pickup for miles up bumpy dirt roads.

Quality

My very first impression and one that has stuck with this bag is the overall quality. Within minutes of opening the bag I was impressed with how well it was made. All the different materials feel strong and durable. The stitching and material connections are very nice, a stark contrast from the cheap discount bags you’ll often find on the accessory shelf at retailers.

I have other range bags that while useful, have quickly degraded. Loosing their rigidity and quality feel. I am hard on gear, likely using it more often than most, and typically with little care. That’s not to gloat, simply an explanation on how gear gets used around here. This Gritr Bag looks like it will be here for a long time, and I have already made it my main range bag due to its great construction.

Get Your Own Gritr Gear Range Bag

Not only does this great bag bring value and order to your shooting, but you can get it for as little as $114 currently with your Amazon Prime account. Delivered faster than some people can draw. Not only that, it comes with a lifetime warranty.

There is more to see about this bag than there is to say. I can imagine if you are like me, you’d rather just get your hands on it and start digging through to see if it fits your needs. That being the case, I’m going to give you my best virtual scrutiny with a variety of pictures. Hopefully this will help you decide if it meets you standards.

Conclusion

I’ll leave you with a few more images in hopes that you can evaluate the bag. But I can confidently say this; it is an excellent buy, and surely the best range bag I have. I can’t imagine someone regretting having purchased it.

Thanks for following along, I hope you’ve found something useful here. let me know if you have any questions or recommendations.

Steiner MX5i 5-25×56

September 6, 2025Optics, Product review5-25, MX5i, rifle scope, scope, steiner, steiner opticscoldboremiracle

Preface

Steiner Optics has a long and distinguished history of making professional grade shooting tools. I have always been a fan of the brand and I’ve reviewed several products here. Today we are looking at another one of Steiner’s popular rifle scopes, the Steiner MX5i 5-25×56. The MX5i has been a popular riflescope for law enforcement and military use during the last decade or so. Today I wanted to see how this popular scope stands up to the other scopes I have used.

The Mx5i Riflescope

The Steiner MX5i is a purpose built tactical scope made with precision shooters in mind. It has all the features a long-range precision rifle would need. The large 34mm tube allow for a full 26 MRAD of elevation adjustment, and houses the large erector housing with fully adjustable turrets. The Duoscale elevation turret has 15 MRAD per rotation, and allows you to reset at zero easily.

Steiner, M5X, desert tech, HTI, 50bmg, — the Steiner MX5i mounted in a **Contessa 34mm Scope Mount**

Inside the MX5i you’ll find the MSR2 illuminated reticle, which I have used in several scopes with success. The FFP reticle is very useful without being too obtrusive, and the ability to illuminate it in low light conditions is also quite helpful.

Included with the scope are some nice flip-open caps to protect the lenses, as well as the typical accessories. As well as the Steiner Heritage Warranty to give you peace of mind. Steiner has moved some of their production to the US which is comforting. In my opinion, the second best place to have a scope built is Germany, and that is where the MX5i comes from.

Shooting the Steiner MX5i

I’ve had the good luck to use this scope quite a bit, which is not always the case when reviewing some products. Having been able to travel the world a bit with the scope has given me some additional insight into its durability. From shooting 50 BMG rifles in the arid deserts of the west, to sub-freezing temps shooting down abandoned Soviet airstrips.

My first experience shooting the scope was on my Desert Tech SRS M2 chambered in 338 lapua magnum. A strong rifle that would show failures in a scope that isn’t up to the task. Zeroing the rifle was easy using the MX5’s turrets. With a simple slip of the turrets I zeroed the elevation and windage.

First Shots

On the first trip out, we stretched the rifle all the way out to 1600 yards. I must say that I was impressed with both the repeatability of the scope, and the optical sharpness. As it happens, after picking out a target at 1600, every shooters dream occured…

Steiner, M5X, desert tech, SRS, srs m2, 338lm,

A lone coyote wandered out of the cedar trees just behind my target zone just as I settled in for a shot. I watched him as he picked his way between the trees hoping for him to pause. After he seemed to show no sign of stopping, I decide to lead him. Having made a dozen or so shots all ready at that distance, I had a pretty good idea of the flight time anticipated. With my lead held I pressed the trigger, sending the 250 grain Swiss P bullet on its way.

My luck with coyotes held true that day, as just after I pulled the trigger he must have sensed a disturbance in his aura or something and he stopped. A moment later and just a foot or two ahead of him, my shot landed right where he should have been. It would have been an amazing shot.

Shooting Abroad

A few weeks later I found myself laying in deep snow looking down a cut in a sea of coniferous forest in northern Europe. My breath would condense and freeze to the side of my rifle, making it somewhat challenging to focus. But looking through the MX5 I could clearly see my targets downrange a kilometer away. The target hangers contrasted clearly against the white blanket of snow.

Over the course of several days we shot targets in the icy breeze, with and without snow falling. It was a great test of the clarity of this scope, never fogging up. It also required me to rely on its accurate tracking, as I was shooting soft targets through falling snow. It was impossible to see impacts.

In Tandem

I also shot the MX5i in tandem with the Andres Industries TigIR thermal sight. This brought another level of perception, looking through both optics together I was able to see my bullet holes appear in the snow even 600 meters away.

Steiner, M5X, desert tech, SRS, srs m2, 338lm, Andres Industries, TigIR, thermal,

You can read more about the Thermal here, but I must say that the Steiner MX5i worked fantastic together with it.

Parallax Adjustment

I love a scope with good focus, and the MX5 does a great job focusing the image properly. The adjustable parallax also allows you to remove parallax from your view across great distance. This was very helpful both on the rifle range, and the desert.

Adjusting the scope in general was smooth and predictable. The clicks of the turrets felt clean and audible. The Duoscale elevation turret is pretty interesting, as you cross the 15 MIL point to the second rotation, the numbers slide up and change to 15 and up.

The MSR2 reticle is a fantastic reticle for this kind of shooting. It gives you plenty of tools for measuring targets and ranging distance if thats your thing. And at the same time it doesn’t obscure your target area. I like the open center dot, it allows for very precise placement.

you can see here how little the reticle obscures your target area

Durability

After having shot this scope over a long period of time across various rifles and calibers, I am quite confident in its quality. Neither my 338 nor 50 BMG managed to knock it out of place. Traveling across the world in hot and freezing climates haven’t seen to do it any harm. It’s never lost zero, and the tracking has never missed. I suppose this should come as no surprise as the MX5i is built on a one-piece tube, with a history of hard military service.

Pros and Cons

Of the many positive aspects of this scope I must say my favorites are these; The robust reliability, the precise tracking and repeatability, and the clear reticle that is easily focused at any distance. These features make this scope an easy choice if you find yourself heading into the unknown. Whether it be against cunning animals or an opposing force.

The only thing I would take away from the Steiner MX5i would be that it seems to suffer in clarity a tiny bit at full power. This seems to be the case for most every scope I use, so its not particularly a jab at this Steiner in particular. But I did find myself often using the scope at 21-22 power for optimal clarity at long-range.

The MSRP from Steiner of nearly $3700 might be a tough pill to swallow for some folks. Even the going street price hovers around $3000 from places like Euro Optic. But if you want military quality optics like this, you can expect to pay for them.

Conclusion

It comes as no surprise to me that this scope performed so well for me. With a reputation like that of Steiner Optics, you can expect great performance. With the MX5i you can expect years of reliable and repeatable shooting with sharp images. Like many others, I can strongly recommend this scope for those interested. If you are looking for something a little more affordable, check out my reviews of the Steiner T6Xi scopes as well.

Hunting with Magnums: Does a Magnum’s Might Make Right?

September 5, 2025blogdeer hunting, elk hunting, hunting, magnumcoldboremiracle

Introduction

As the old saying goes; might makes right. Meaning that those with power can enforce their will. This doctrine has long been used when it comes to hunting cartridges. With hunting season right around the corner we figured it was worth the discussion to evaluate the premise. Does a magnum’s might make right when it comes to hunting? Does the heavy energy load of magnum cartridges make them the best choice for your hunt? Let’s get to the bottom of it.

I load my own with these **RCBS dies**, this allows me the ability to customize the energy applied

What Makes a Magnum?

Magnum cartridges are simply larger than typical cartridges of comparable bore. For example, the 30-06 Springfield is a common 30-caliber cartridge. The 300 Winchester Magnum is a larger 30-caliber cartridge, with more powder capacity. This allows the 300 to push bullets much faster all else being equal.

the 30-06 Springfield has been and will continue to take nearly any NA big game animal. This **Winchester model 70** is a classic example of an American hunting rifle

The whole premise of magnum cartridges is to bring higher velocities and energy. When you shoot larger bullets and faster velocities the energy imposed on the target goes up. This can be very important when it comes to hunting animals, as energy is key to quickly incapacitating our prey.

Ballistic Performance

Another reason magnum cartridges are popular is because of their ballistic performance. The same attributes that make them effective for hunting, also make them effective for long-range shooting. Being able to shoot bigger bullets at faster velocities, or standard bullets at even faster velocities makes them a better choice for shooting further. Heavier bullets and faster bullets hold onto their energy longer, which pushes out the envelope of their effectiveness. You can imagine how this would be helpful to both a hunter, and a long-range shooter.

Magnums like this 300 PRC do well for long-range shooting and hunting

Newer and better bullets are constantly hitting the market, which is making the ballistic performance grow ever better. The 180 grain bullets your grandpa shot weren’t as efficient as the latest and greatest 180 grain bullets we have today. But does that matter for many of us?

Real World Applications

As I peruse hunting and shooting forums, social media groups, and even the slums of reddit, you can get an idea of most hunting practices. It seems that the majority of hunters typically engage big game like deer at distances between 50 and 400 yards when hunting with firearms. Obviously that depends greatly on location and the animal they are after.

deer sized animals can easily be taken with smaller calibers like this 6mm GT in my **Desert Tech SRSM2**

If you are stalking a fifty-pound Roe deer on the green fields of Great Britain, you will probably use different tackle than a hog hunter in Georgia, or a Stone Sheep hunter in the Yukon. The size of your prey, and the environment you pursue them in has much to do with your cartridge selection.

Even large animals like a Rocky Mountain Elk are easily taken with short action cartridges like a .243 or a 30-30. So why do most people use heavy magnums for hunting them? Mainly because Rocky Mountain Elk live in places you don’t want to take your .243.

The Landscape

Western hunts often take place in big open country, where shots could be much further than average. Furthermore, a wounded animal might go for miles through the steepest miserable country you can imagine. So it makes sense to use a rifle with more power and heavy bullets. In many of these hunts, it is also important to drop the animal right where it stands to avoid strenuous extraction.

when hunting in the deep forest, you often want to secure your prey where it stands to make it easier to get out

Conversely, if you are hunting one of the gulf states you probably aren’t going to be making many 400 yard shots. And your chances of finding an elk down there are likely limited to exotic ranches. Consideration to location could have a lot to do with whether or not you really need a magnum.

Biology

It is also very important to understand the body structure of the animals we intend to hunt. Some animals are tougher than others, and require a little more energy to quickly and cleanly put them down. Using an appropriately proportioned cartridge for the animal not only ensures a clean kill, but also reduces waste. I like to eat what I hunt, so blowing a deer in half with a super magnum is not on my list.

Hitting an animal in the right spot is more important than what you hit them with, read more about that here

Using a magnum on a small animal particularly at short distance is likely to cause more damage than necessary. This could cause meat to be lost and discarded. Shooting a 90-grain bullet from a 6mm Creedmoor might be perfect for hunting a Pronghorn antelope inside 400 yards. You could use a 300 Winchester for the same job, but you might have a few pounds less to take home for the freezer.

The 6.5 Cartridge Dilemma

September 3, 2025blog.264, 264winmag, 6.5, 6.5 creedmoor, 6.5 Grendel, 6.5 pR, 6.5 remington, 6.5x284, 6.5x55, cartridgecoldboremiracle

Introduction

Many Americans seem to have been born with a .30 caliber fixation, nothing to be ashamed of believe me. But there is a rivalry coming for America’s top spot, and its coming from the metric system believe it or not. 6.5 caliber cartridges are nothing new, even in North America. Today we are going to discuss a variety of the 6.5 cartridges and why they have such a cult following that continues to grow. Perhaps by the time we are done, you might feel a taste for the 6.5 Koolaid yourself.

6.5 or .264?

I remember speaking to an old gunsmith who claimed to have trained under P.O. Ackley. He told me that allegedly Ackley believed the 6.5 to be the ideal bore for accuracy. I believe both of them were simply a product of their time, and I also believe there isn’t an “ideal bore”. Instead there are simply perfect proportions, bullet lengths and angles as compared to the bore.

What you cannot deny is that 6.5mm bullets (or .264 inches for the Yanks) typically have excellent ballistic coefficients (BC). And these high BC bullet are usually easy to get up to excellent speeds due to their weights. Most 6.5 bullets fall within the range of 100 to 150 grains.

Whether .264 or 6.5, there is an incredible variety of cartridge cases designed to push them. And choosing which one of these cases is incredibly important as to the performance. A diminutive 6.5 Grendel can shoot the exact same bullet as the massively overbore 26 Nosler, but the performance will be just as distinct.

The Rise of 6.5 Cartridges

Back in the late 19th century, the 6.5 craze had already begun in Scandinavia with the 6.5×55 Swedish. It was used widely for so many purposes and in such numbers that it spilled into other firearm markets. For over a hundred years the Swede’s have been taking moose and reindeer with a 6.5. This might be downright shocking if you are one of those who uses a 300WM to pile up a 110-pound bean field whitetail from a ground blind.

It took some time for the 6.5’s to catch on across the American heartland. Ballistic tinkerers like the aforementioned Mr. Ackley made wildcats like the 6.5-06 popular. There were others like the 6.5 Remington magnum, but they didn’t catch on like their designers had hoped. It was like trying to sell a bullpup to Americans who love AR15’s.

One of my favorite cartridges for largely sentimental reasons is the .264 Winchester Magnum. A product from the 1950’s, it actually predates its 7mm twin, the 7mm Remington Magnum that gained far more attention.

Modern 6.5 Cartridges

Most of us are likely more familiar with modern 6.5 cartridges, but which one will best suit your needs? Many people love to hate on the 6.5 Creedmoor, but it’s impossible to deny its versatility. And it’s literally a ballistic twin to the 6.5×55 and we’ve already discussed how useful that cartridge has been and still is today.

Over a decade ago, there was an outright brawl between the three most popular 6.5 cartridges in the precision shooting space. The three protagonists were the 6.5 Creedmoor, the equally new 6.5×47 Lapua, and another American classic the .260 Remington. All three were hugely popular for short-action precision rifles, but the Creedmoor has seemed to win the popularity contest. Each of them had their strong points, but there’s nothing wrong with any of them.

The newly popular 6.5 PRC has gained an impressive following among big game hunters. While it often shoots the same bullets as the Creedmoor, it shoots them much faster. With a four to five hundred feet per second advantage, the PRC is lighting on deer and elk.

In long-action cartridges, Nosler more recently released their 26 Nosler cartridge. With a huge powder column, it is made to move fast. Of course this comes with a Nosler sized price tag as well.

Considerations

All of these cartridges have positive attributes that you should consider for your purpose. Whether you are a casual hunter, a serious competitor or even a Law Enforcement sniper there is something for you in this family of cartridges.

If you find yourself shooting deer or other comparable game within ranges of two to three-hundred yards any of them will do. One of my kids will be hunting with a 6.5 Grendel this season, shooting 120 grain bullets. Another of my kids will be hunting with the same little .260 I built for him when he turned 12.

My brother and I both will be shooting 6.5 PRC’s most likely, which are definitely good for a bit more distance. We’ve both taken .260’s and Creedmoors beyond the 1,000 yard line, but the PRC is a better tool for such a task.

My father would be shooting his .264 Win Mag, which he’s used in the past to take mule deer, antelope and mature bull elk. Sharing a ballistic profile with the 6.5 PRC it too has a more useful range envelope.

Preface

Holsters can be as subjective as the guns that go in them. You might try five different holsters for your preferred pistol before finding one that is just right. I’ve been playing with holsters a lot lately, and today I wanted to share another one with you. Todays subject is the Gritr Gear Omni Holster.

The Gritr Gear Omni Holster

The Gritr Gear Omni Holster is a simple Kydex design, optimized to be configured however best fits your needs. It can be used as an IWB holster, or an OWB holster. It can be configured right or left handed, and is available for most popular handguns with or without optics cut.

For my purposes I figured a Glock pattern would be optimal, as I have various Glock 17 and Glock 19 clones that would allow some evaluation. You can order the Omni holster to accept popular weapon light options like the SF X-300 or SL TLR-7. The Omni holster also came with a belt mount, allowing you to attach it directly to your belt and adjust the angle as well.

The Omni comes with a concealment strut on one side that rides under your belt to help keep your pistol tucked when concealing. It is both reversible and removeable for different carry styles, but I saw no reason to take it off.

Configuring the Gritr Omni Holster

I would end up using the Omni in various configurations because I can. Both inside the waist belt (IWB) and outside the waist belt (OWB). The single belt-clip can be adjusted for ride height, so you can customize where your pistol sits. It can also be swapped to the opposing side should you need a wrong-handed draw. The clip has a nice retaining lip to prevent you from pulling the holster out when drawing the gun.

There are also tension screws that allow you to adjust the squeeze of the holster to increase retention as needed. There is no secondary retention, just the friction of the holster’s squeeze. We found that this was adequate for keeping pistols secure in the holster. During testing we tried various G17 and G19 sized pistols with great results.

We also tested the Omni on a typical gun belt, using a Safariland QLS fork for attachment. This was a great option as it allowed quick removal and install from various belts.

Shooting From the Omni Holster

Drawing a handgun from the Omni holster was slick, just as its designed to be. The holster give generous space for sights to avoid any occlusions, and the Kydex covers all the important parts. Drawing the pistols from the holster had very little resistance, making it quick to get on target. Especially from the OWB configuration, as I am used to retention holsters and having to grip a release. This was much faster, simply pulling the pistol out an presenting on target.

As typical, there is a touch more to consider when drawing from the IWB position. Lifting clothing and avoiding snags requires a little more diligence. I do like how the Omni covers up everything; trigger, ejection port and more are covered by the Kydex “ears” that come up the side of the slide. It also protects you skin from slide serrations and other parts of the pistol that might cause discomfort.

All the pistols I tested in the holster were G17 or G19 clones, and they had a similar feel. Only the differences in slide cuts seemed to change the resistance when drawing the pistol.

Final Thoughts

The ability to configure this holster makes it and easy choice. I could even see getting a couple of them for various purposes due to their low cost. Whether you want to mount them to your belt, or just tuck them under your shirt it is pretty straight forward. The various mounting holes also allow you easy alternative mounting solutions. Overall, the Gritr Gear Omni Holster offers an inexpensive option that can be applied easily to just about any carrying need. And getting one drop shipped to your door using your prime account makes it that much easier.
