ES Tactical 6.5Creedmoor Barrel for the MDR

Just when I thought I was up to my ear’s in MDR, Eric Smith from ES Tactical found it expedient to dump another huge helping of MDR in my lap. It wouldn’t take long to figure out which way this would go.

As a guy with too many irons in the fire already, I took the 6.5 Creedmoor barrel with a grain of salt (I know you all feel my pain). Had it not been for my stellar experience with Eric’s work, I might have even backburnered this project. But instead, I took the first opportunity to stab my MDR with this latest addition to the pile.

Ive shot the MDR quite a bit, some might even say more than anyone else. The MDR is a multi caliber bullpup rifle. The rifle was first available in 308, it will soon be available to the public in 223. But for those of you that already have the gun, you can wet your multi caliber whistle without waiting by ordering a 6.5 Creedmoor from ES Tactical. I shot quite a bit of 308 in the beginning, and I loved having so much power in such a little package. With the 308 barrel installed, the MDR can put down a serious amount of hate and anger. But it is still quite capable of MOA accuracy, and at distance as well. Just a short while ago, the 223/556 conversion was made available to me. In the short time I spent with it, I became very enamored. The minimal recoil, and outstanding accuracy made the compact MDR even more desirable, you can read more about that here.

So you can imagine my excitement when the option came to try out the Creedmoor in my beloved little rifle. The Creedmoor offers the same accuracy as the other cartridge options, but less recoil than the 308, and a better envelope for distance as well.

I couldn’t resist the appeal, so I hurried up to my local shooting hole, and warmed up my trigger finger. Upon arrival I ran a few magazines of 223 through the rifle, just to get my trigger finger into shape, then set to swap the rifle over to the Creedmoor.

Since the 6.5 and the 308 share the same boltface, magazine, and a few other parts, there is only a need for a barrel assembly should your rifle be a 308. Since my rifle was currently a 223, I had to swap bolts, remove the magwell block and switch the magazine catch.

It took a few minutes, and I was ready to make some noise. Except I wouldn’t. I hate shooting without the proper muzzle accoutrements, so I attached one of my favorite suppressors, the Silencerco Hybrid. The barrel assembly from ES Tactical came with a six position gas key, allowing for refined tuning of the rifle. I found it quite unnecessary to figet with, as the rifle functioned flawlessly, it consumed and expelled everything I fed it.

Speaking of diet, I tried a few different things. I started out with Desert Tech munitions 140 grain match, I have always had good luck with it, and today was no exception. I also tried some of the more popular brands, such as Hornady 120 Grain Match As well as the gold standard Federal Gold Medal Match 130 grain And the very popular Prime 130 Grain Match

The accuracy results from this fine selection varied slightly, the DTM, and Hornady gave the best results. Both of them printed groups that were mostly hole, and little paper. The Prime and Gold Medal were not too far behind, it is my guess that the Berger and Norma 130 grain bullets used may perhaps be a bit more finicky with seating depth. Which may explain the larger patterns. DTM shown in blue, Hornady in red, Federal in yellow, and Prime in green

As you can see in the groups the stringing is horizontal on the better ones, it seemed to follow the heating of the barrel. The first three or four shots in each group were either touching or stacked. It was usually the fourth, fifth or sixth shot that were the outliers (I may have lost count a few times, I was enjoying myself😌). The lesser groups didnt seem to have any particular pattern. I only ran a chronograph on the DTM 140 grain ammunition, the average over a couple magzines worth of ammo showed 2610fps. I was quite pleased with the velocity from this 18 inch barrel, with a MV like that, coupled with MOA or better accuracy, this thing would be very useful for anything inside 1000 yards.

Being as familiar as I am with the platform, I have gotten used to it’s quirks and folleys. This familiarity has helped me avoid some of the little things that cause malfunctions, so it didn’t surprise me at all that I experienced no failures. I did note that the brass was coming out pretty dirty but otherwise fine, I suppose I could have dialed down the gas pressure a little after all.

In total, I shot probably 80 or so rounds (not counting the 223 appetizer). It was smooth shooting, the recoil was very mild, and with the suppressor mounted up, I could shoot all day. This setup would be awesome for a threegun carbine, it’d also make the perfect truck gun, or patrol rifle. So many possibilities, I doubt it will be long before the next flavor MDR comes along.

Should you find youself in need of a Creed for your MDR, give Eric a call over at ES Tactical, and dont forget he cuts awesozme barrels for your SRS, or just about anything else you might want too.

6.5 Creedmoor

It’s no secret that I am a fan boy for the Desert Tech Stealth Recon Scout, I have spent the last few years getting intimately familiar with its virtues. I have had the chance to use the SRS in many different applications, including hunts of all kinds, as well as competitive, and long range shooting. Today I am writing about one of the many reasons why the SRS system, with its seemingly unlimited options has replaced every other rifle in my safe.

I jumped onto the 6.5/.264 bandwagon a couple years ago, it was a 26” 260 Remington that sealed my opinion of the .264 bore. That original barrel has around 3000 rounds on it, and the bullets it has fired have crossed untold miles of cold mountain canyons, and hot desert plains.
The 6.5 lineup has grown over the years, too many to mention here, but the bulk of the work is done by the 260 Remington, 6.5 Creedmoor, and the 6.5X47 Lapua. We could debate for days (and we often do) about which one of the three is best, and why. But today, I have chosen to focus on the 6.5 Creedmoor.

I appreciate the aesthetics of properly manufactured ammunition, and the Creedmoor loaded by Desert Tech Munitionsis a perfect example. Clean and smooth edges, the discoloration of annealed brass, and a uniform presentation that gives a consumer confidence. Looks certainly are not everything when it comes to ammo, so I wasted no time getting to my shooting position.

It was a cool and breezy evening, a snow storm was inbound, threatening to soak my target, my SRS, and of course me. None the less I hiked with purpose to the spot I go to when time is short.
A quick shot of the rangefinder confirmed my one hundred yards to the target, I found a comfortable position with a good solid rest.
The barrel I was using to test this ammunition was virgin, I had only finished its assembly an hour or so before I left work. So a zero had to be achieved before any accuracy testing could be done.
I opened the first box, and loaded ten rounds.

My first shot landed about 1.5 inches low, I measured with my reticle, and made a corrective adjustment. The next 8-9 shots went into one ragged hole, and but for one shot that I knew was bad when it broke, it was as good as anything I’d ever shot previously. That is of course not saying much, as I’m terrible at shooting groups. But even for me, it seemed quite easy to stack shots on top of each other. I continued to shoot five shot groups one after another, I was more than happy with the patterns that this ammo made, through this brand new barrel. I’m very interested to see how it does after its broken in.

After shooting a few boxes of ammo at 100yds, I called it a day. The snowy weather was making it hard to see anything, and the wind was starting to get worse. So I retreated back down the mountain trail, suspending my testing temporarily for a better day.

As soon as permissible, I made my way back up into the mountains. A few days had passed, and the blue sky stretched as far as I could see across the valley. I made my way up the winding mountain road, my ATV laden with a days’ worth of gear, snacks, and snow. As I climbed higher and higher, the snow got deeper. But silence and solitude was the reward. When I finally found the spot I wanted to shoot from, I had gained nearly 3,000 feet more than my first outing with the Creedmoor. Nothing but a light breeze and sunshine at that altitude.

Again I setup my target at 100 yards, and did a quick zero test. I was pleased to see that my cold bore shot was exactly on my point of aim, and the several shots that followed were right on top of it. Happy that nothing had changed since my last outing, I decided to push the Creedmoor out a bit further. I started at 642 yards, I wasn’t about to walk that far in the deep snow. Instead, I found a small cube shaped rock on a small exposed piece of dirt across a long draw. I estimated the rock to be two or three inches in width, a reasonable sized target for that range. So I set to getting the wind and elevation for the shot. I wanted to see how close the come ups listed on the box were to actual , so I made an estimation from the data printed there, and made a wind call. I loaded the magazine as I went over everything in my head, then settled in behind the rifle. I focused on my trigger pull, and broke the shot, the impact was right at the base of the small stone. I made a small correction hold, and sent three more shots at the rock. All of them found their mark, smashing the rock, and sending its pieces rolling into the snow below.
I repeated the process at 860 yards, and again at 970. I was very impressed with the accuracy, shot after shot was right where I had aimed. And when it wasn’t, I knew it before the rifle had finished recoiling.

Obviously, I am a bit biased in most of my opinions here. But I can certainly say without any bias, this is the most accurate factory ammunition I have ever shot. Consistency is king in this game, and I cant wait to keep stacking shots in the black with this Creedmoor.
