6.5 Creedmoor in AR platform?

Anyone here have experience on the 6.5 Creedmoor in the larger AR platform? I see DPMS has discontinued it. Were there any problems inherit to it, feeding, accuracy, etc.? Or is the 260 just more popular?
TIA
 
I would think that the 6.5 creedmoor would be better suited in an AR platform because its OAL is shorter typically than the 260 rem and thus, easier to mag feed.

From what I hear, a lot of guys are starting to do this.

8541 tactical I believe is starting an AR build that he posted on youtube and it is using the 6.5 creedmoor.

Accuracy should be sub-1/2" groups at 100 yards with match/tuned handloads IMO.
 
My buddy just bought a 6.5 Creedmoor on an AR platform from Lancer Systems in Allentown, Pa. It's pretty sweet.

I think it was a limited run, but if you have your heart set on one, let me know and I can get you the armorers contact info.
 
Go to JP rifles and read his reloading section. He calls them both the same ballisticly. And gives the same load for both. Why put up with crappy brass and expensive dies?
 
I have one that is just minus a few parts from completion, waiting on a handguard and lower parts kit at this time. It has a custom 24" McGowen tube, medium heavy profile (.800 from the gas block to muzzle, .875 gas block, .940 to the chamber, rifle gas system, 1/8.5 twist), DPMS upper/lower, and CMMG MK3 bolt carrier.

I have had pretty good luck with accuracy in the AR platform - my 18" 308 AR frequently shoots sub-MOA, and I think with a custom tube and careful handloading this one should at be able to beat it. I think the 6.5 Creedmoor + AR platform are a great combo - even long 140-gr bullets can be satisfactorily loaded to mag length.

As for loads, I am planning on running the 123 Amax and 123 Scenar over H4350, and I hope to achieve somewhere in the 2950 fps range.

I would not hesitate to build one - if you want to get one running immediately, I would look at the 24" Criterion tube that Fulton Armory sells, or a JP 22" one. Both could be in your hands quickly, unlike the almost 5 month wait it took to get my McGowen.
 
Woo Hoo, finally something I have full experience in.

I love it. Of course I grabbed a DPMS Upper in 6.5CM with 24" bull barrel and I've had great results.

I'll leave it to the OP to research the difference between 260 and 6.5CM, however, I'm shooting the 142gr Matchkings at 2.800 COL mag feeding with no trouble. 1/2" groups are doable at 100y (if you want I can take pics of my targets and post them).

I think the cartridge is being dropped for lack of interest, though it is a little easier to get the heavies seated to mag-length (I don't own a 260, I just read that somewhere). I really love that with 260/308/6.5CM I can use the same mags. Makes it easy when I bring both my LR308 and 6.5CM to the range.

Dies are really cheap, Hornady has a 6.5CM FL bushing die that accepts Redding bushings, and their seater is already prepped for VLDs.

Hornady brass is very good in this, but you can form some form .243 if you're interested. Hornady also has very decent factory ammo if you can find it. The 120 A-Max or 140 A-Max have been used in comps. Again, it doesn't take much internet searching to find the same results I've found.

Exactly!

Doable, but plan on a JP (or other) adjustable gas block. In my experience my gas guns run better at under a full-load. Example: My 142SMK at 2.800" COL with Federal 210M needs 39.8gr H4350. No chrono, but Come-ups suggest 2650fps. From that load I would estimate my 123gr node to be more 2800 than 2900, but you know how it goes every barrel/rifle are different.

Just finished mine a few days ago. I'm using the JP barrel, their adjustable gas block, LMOS bolt and captured spring system with tungsten weights. Built on the MATEN, Megalithic receiver set. Will be using 123 gr bullets and H4350 as well. Just need some warm weather to have some fun.

 
I think you will be very happy with the Criterion barrel! I put together a 308 AR for my brother with one of the 20" M110-profile barrels, and it is a tack driver. It also doesn't foul at all, came with a properly sized gas port, and runs with 100% reliability.

Another important thing that is helpful for brass longevity and running hotter loads is 1) getting the rifle gassed appropriately, and 2) enough buffer weight/spring. I had a rifle that would show ejector swipes and cratered primers with even mild loads. After switching the buffer and getting it gassed correctly, the brass looks hardly any different than it was fired in a bolt action with no cratering of primers or swipes.

Ltdshooter, that is a beautiful rig and alot nicer than mine! Are you going to be running the Amaxes as well? I have been tempted to give some Berger 130's a shot too...
 
I'll start with the 123 Amax as they are plentiful and pretty decently priced. A good friend of mine just built one close to mine and he is getting outstanding accuracy with the 123 Amax and Vhit N140. (.3s at 100yds) I'm going to go with H4350 as it seems to be the standard and have some on hand. Will try other powders and bullets if needed.

When you say "gassed correctly" I am assuming an adjustable gas black and cutting it down to just above not short stroking?

Yup, that's it. Adding mass to bcg, or buffer and or a stronger spring also slows down the timing.

That is the adjustable buttplate assembly from Modular Driven Technologies. It can be set for pad height as well as cant in addition to the LOP adjustment the PRS comes with and makes a huge difference in the fit and feel of the stock.
