Got some Priv Partisan 7.62x51 ammo for my Rock River LAR-08 and cannot get a single cart to feed correctly. When the bolt racks forward, it won't completely close, which locks up the charge handle and leaves me to butt-slam the gun while pulling on the charging handle to remove the "stuck" round. I broke the gun down and the rounds drop into the chamber just fine. Miked the cases and the dims are all within spec, maybe a hair on the small end of tolerances. Strangely, every round I've touched has small burrs on the butts and necks of the brass. Disassembled the bolt and found the spring loaded pin opposite the ejector clip is very stiff, to the point where it could be strong enough to not allow the bolt to slam forward enough to lock. Rock River says it's the ammo, and it could be. Gonna try a bud's store bought stuff tomorrow. Anyone else experience this with a .308 auto or other foreign ammo?
TIA!
