So I have an AR10 that I built with a Proof Research 24-inch 6.5 Creedmoor barrel. I have about 450 rounds down the barrel and accuracy has been stellar, however over the course of those 450 rounds I've had 3 instances of a case getting stuck in the chamber. Accuracy has been awesome, with this barrel my AR10 can hang with my bolt guns, but the reliability issue really kinda drags down the performance.
I'm currently using Hornady Brass that was initially fired in my bolt gun a few times, full-length sizing it, bumping the should back 0.005, and shooting a light/medium load.
Is this likely a situation where I just need new brass that is specifically for the AR10 or has anyone else experienced tight chambers on their Proof barrels?
