22 creedmoor loads

[venatic]

I know this is a year old but there are few posts about this caliber.

I've been running one for over a year now using 6 Creed Hornady brass. I've been getting around 3500 fps with an 82 grain Berger. A month or so ago I loaded Lapua 22-250 brass with a 77 TMK and 39 grains of R26 and it resulted in a perfect 22 Creed case. I worked up a load today with that brass and was able to fill the case (47 grains) with R26 with zero pressure signs. 66 grains gave me 3561 FPS and 66.5 gave me 3589. The two groups I shot with each were .299" and .235" at 100 yards.

I have been loading the 22 Creedmoor for 3 years and I am pretty sure 66gr of R26 won't fit but maybe you meant 46gr which is a little over max in my rifle but I use Lapua 6.5 Brass.

Yes, I meant 46.

Where should I look to source a .22 creedmoor bartlein chambering for an AR10?

If you're looking for a cheap drop-in ready to use AR10 barrel, you might out of luck.

Bartlein is not making AR10 or 15 barrels anymore:
https://bartleinbarrels.com/ar10-and-ar15-barrels/

They suggest:
https://308ar.com/craddock-precision-ar-10-308-ar-barrels/

Otherwise call your friendly barrel supplier to see if they can conjure one up in a short time.

If you want the best performance from any of the Creedmoor cartridges in an AR platform you really should look at the Proof Barrels CamGas barrels in stainless steel (not carbon fiber...)
