Cayuga solid copper bullets: 6mm 100 grain

Some of you may have already read about my experience with the 6.5 Cayuga from a year or two ago. That may or may not have led you to this subject, but if you are seriously looking into the Cayuga as a hunting bullet then I’d recommend reading both articles.

The Cayuga
All Patriot Valley Arms Cayugas are solid copper monolithic bullets, lathe turned to perfection from the same alloy as traditional copper cup bullets. This allows them to be extremely consistent from bullet to bullet, and the CNC turning process also allows their profile to be controlled meticulously. The Cayuga solids boast much higher ballistic coefficients than comparably weighted bullets, but due to their lighter weight from lacking a lead core they can be shot at higher velocities. So to sum it up; higher bc’s and lighter weight make them better for distance shooting and the lot consistency and gentile ogive make them accurate and easy loading.
Earlier this year, I started my second six millimeter project, a 6mm GT for my Desert Tech SRS M2. It took only a few minutes to fall completely in love with the Tiger, so when given the opportunity to test these new Cayuga bullets in it, I wasted no time. The 6mm GT easily pushes hundred grain bullets to the 3,000 fps mark, and the high BC of the Cayuga meant that it would hold onto that velocity and energy for quite a ways.


The Numbers

The 100 grain Cayuga didn’t exactly come with an owners manual, PVA gave me some suggested data to work with which seemed to be spot on. I used a G7 BC of .270 which is very similar to the extremely popular Berger 105gr. I tested the Cayuga to beyond 1400 yards and as far as I shot with it, that .270 lined up perfectly.

Easily Loaded
Once I had the Cayugas in hand, I sat down at the loading bench to get busy. The go to powder for the GT is Varget, and for good reason. But if your reading this in the same era it was written, then you know how hard its been to get certain loading components. Varget was hard to come by, but I had eight pounds of Reloader 17 that I could make work. And boy did it!
The very first load I tried with the Cayugas was a modest charge of RL-17 that produced around 2960 fps from my twenty-four inch barrel. The first five bullets I tested went through nearly the same hole, I shit thee nay. Groups in the .2’s and .3’s were immediately achieved with ZERO load workup or seating depth fiddling. While I do consider myself to be both lucky and handsome, I think the generous curve of the bullets ogive likely bears more credit for the accurate shooting than any luck of my own.
I added a touch more powder to break the big three-o, and left the rest alone. From there I spent the rest of my test shooting validating drop and such to confirm the bc. The end goal here was the same for nearly every project of mine; what can I kill with it?

Hunting Season
The GT had accompanied me on a bear hunt to Montana, no kills were made there so the next opportunity would be the Mule deer hunt in my state of Utah. The Rocky Mountains that I call home are quite spacious, and the steep and deep canyons where we hunt our deer can often stretch for miles. Shots can be anywhere from one hundred yards, out to two or three ridges away. To put it simply, a five, six or seven hundred yard shot on a mule deer buck is about as common as anything. The Gay Tiger loaded with Cayugas had become such a predictably accurate shooter that anything in that realm felt like a chip shot as far as hitting my point of aim. So when opening day arrived, the GT road right next to me, and never left my side. We ended up using it for two separate shots on deer, both of which hang quietly in the shed in my backyard.
The first deer was shot at six-hundred and eighty yards, it was a perfect broadside shot that passed through leaving an inch and a half hole on its way out. The deer staggered about twenty yards before he tipped over.

The second deer was taken a few days later, at a distance just over a thousand yards. He too took a single shot and dropped straight to the ground where he expired. While the second shot may have had less energy than recommended by many, it certainly did the trick just fine.
Broken rib bones, shredded lungs, and bright blood stains against the dry yellow grass are exactly the kind of indicators that good hunters like to judge a bullet’s performance.

Conclusion
Just as I had expected, the 6mm Cayugas are everything I had hoped for. Accurate and flat shooting bullets that make an impressive wound cavity through animals. We often joke that Im going to have to shoot an elk with a 6mm Cayuga if ever I want to find a fired one. But after seeing what I have, it’d have to be really far away, or else I’d have to shoot him length-wise. We killed seven deer last week, just in my group. And the 6mm GT shooting Cayugas killed every bit as well as the larger cartridges used (6.5CM, 260, 308). If you are in need of a solid copper hunting bullet, or if your stuck in California for example, the Cayugas are just the ticket for six-millimeter big game hunting.

PVA Cayuga Solid Copper Hunting Bullets

The good folks at Patriot Valley Arms helped get me started down this road, what seems like a very long time ago. Good people and good products are the norm for PVA.

The 123 Grain Cayuga loaded into Petersen brass

I was given the opportunity to test drive PVA’s new 6.5 line of solid hunting bullets. Hunting is my bread and butter, so I was excited to put these lathe turned solids into action.

The 123 grain Cayuga bullets are turned from solid copper bar stock, using the same alloy of copper that jacketed bullets use. Turning them on a CNC lathe gives precise control to bullet geometry, it is this precision cut construction that gives the Cayuga its uniformity.

The bullets are solid copper, with a hollow point cut into the tip. They have a tapered boat-tail, and a driving band around the middle. The gentle taper of the ogive makes these bullets very generous when it comes to seating depth sensitivity.

I cautiously loaded these bullets into some 6.5 Creedmoor brass from Petersen, with a goodly charge of H4350, and took them to the range. Initial groups were easily sub MOA, and with little adjustments, I had them shooting around half an inch.

It was time to hit the track on this test drive, a Rocky Mountain Elk hunt. Some might think that a 6.5 Creedmoor is a bit light for elk, which it may be. But I’d hunted with similar setups plenty of times in the past, so I wasn’t worried.

The first elk to fall to the Cayuga, hit at 475 yards

The first engagement we had with an elk took place at 475 yards, a young cow stood quartering away. The bullet hit her at the top of the left side rib-cage, on a slightly down angle. It passed through the ribs, passed through her lungs leaving quite a mess, and exited the front of her chest just to the right of her neck. She dropped immediately, and slid down the snowy slope. Damage was exactly what I expected to see from such an acute injury. Broken bones, spalling through tissue, leaving mayhem in organs which could no longer sustain life.

These lungs stood no chance, ripped open by the passing bullet

The second Cayuga fired at a big game animal was a mature cow elk, chewing away at the brush bark on a cold winter storm blown mountain. She was 520 yards away this time, completely unaware of the heated copper cutlass headed her way. It again impacted in the ribs and shoulder, breaking both the shoulder blade, several ribs, as well as one of her vertebrae as it passed by. She instantly dropped, and bled out as quickly as one would expect.

Again the lungs were damaged beyond function, both animals quickly succumbed to their injuries

The damage done on both animals was very proportionate to the size of the expanded Cayuga, unfortunately both of them blew right through the animals so I was unable to see their final dimensions. Never the less they did a perfect job, and I couldn’t have asked for more.

If you are in need of an all copper hunting bullet, or if you want a hunting bullet with an extremely high ballistic coefficient, then give these Cayuga bullets a good look. When the shots count the most, send something that brings it all. For additional info, read my article about the 6mm 100 grain Cayuga

Patriot Valley Arms Jet Blast Muzzle Brakes

I often talk about how we are living in the best times of precision rifling, part of that is because of technology, and also due in part to the thriving market of suppliers bringing great new products to us.

Patriot Valley Arms is one of those manufacturers, pushing the envelope and innovating products for shooters, And today I’d like to discuss their Jet Blast muzzle brakes.

Muzzle brake technology has changed significantly even since I started paying attention, I remember the first muzzle brake I ever had installed. Back then there was a simple purpose, reducing recoil. Radial porting around the whole barrel that blew dust all over, made it even louder than it was before, but it did tame the recoil. We have come quite a ways since then.

The Jet Blast Muzzle brake comes in a three port design, with baffles directed to the sides and back. The Jet 4 brakes have an additional port for a total of four, giving additional braking force. Both three and four port brakes are available with an up to 6.5mm bore, or an up to .308 bore, this gives most shooters a close enough option for their rifle. They are also available finished in stainless, or nitrided black.

One of the handiest features of the Jet brakes is the built in timing apparatus. There is a counter threaded jam nut built right into the back of the brake, which allows you to time the brake easily and quickly. With nothing more than a cresent wrench or something similar, you can set the brake and snug it up. And just as quickly you can pull it off and switch it to another rifle to enjoy its braking qualities there as well.


The curious design of the Jet Blast brakes, creates an interesting pressure flow. I’m certainly no engineer, but the seeming delay of pressure wave created by the brake is just enough to get the shooter through the shot. What I mean by that, is that after the shot, and impact, you feel almost like a delayed cyclone of air passing by you. This must be by design, to give the shooter less antagonizing from muzzle gasses. The loud report from brakes seems to be lessened from the shooters perspective, which is a very nice added value.

If you find yourself in the market for recoil reduction, do yourself a favor and check into Patriot Valley Arms and their Jet Blast brakes. Excellent recoil mitigation, easy install, all for a reasonable price (starting at 135$). Tell em I sent ya.
