I have a new AR-10 with a 260 Rem barrel, I have a lot of trouble with getting loads to cycle in the rifle. rifle came with a gas port. I shoot 120, 123 and 130’s, my powder is IMR-4350 and IMR-4064, CCI-BR primes, Star line brass.

Enabling the BCG to cycle WITHOUT any gas rings allows for the BCG to unlock and move freely to the rear resulting in smaller vertical displacement to the height or within the height of the x-ring.

After modifying the bolt to work without gas rings the accuracy is there and just as good as the little Ar 15.

Problem lies within the gas rings having to much drag and carbon build up as well. The more you shoot, the more it builds up. Any sticking or binding in unlock of the bolt and rearward traveling BCG causes higher pressure in the barrel and vertical displacement suffers.

I read the accurate shooter article on the ar10/260 rem.The reloading data was for a Savage bolt rifle.Anything close for an ar?

What brass are you using since you listed your primer as a CCI 450 (small rifle primer)?

Editor: That should read CCI 250, large rifle mag (sorry). I used Lapua .243 Win brass necked up mostly, but I also tried Remington .260 brass, which worked OK if sorted for neck thickness. This was before Lapua .260 Rem brass was available.

We received AR10 kits for Team Armalite in the mid-90’s and assembled .260 Rem match rifles based on that platform (w/Krieger or Obermeyer barrels), specifically to shoot the Nationals. It took a lot of effort to make them shoot to the level of the tried/true AR15 platform. Ended up switching back to the .223 for Perry and shot the high score on our team. The excitement factor for the 260Rem-AR10 was diminished, at least for us. Nobody stuck with them after Perry.
