AR10 Break in ( Not the barrel)

[cal50]

Kind of a general survey question for .308 AR shooters. I recently fired my Armalite AR10 NM rifle and did the factory hokey pokey barrel break in ( no flames please, I had spare time). Off and on through about 30 rounds I had some short stroking or the bolt not being retained back are the round fired.

I had it lubed up but not flooded. Anyone have similar short stroking with a new rifle and if so how many rounds to get it smoothed out? My gun was drier than a pop corn fart in the desert.
I was popping off 168 Sierra's and grouped nice with my barrel swabbing aerobics.

Factory ammo or hand loads using 168's? If hand loads, recipe?

Federal factory 168.

I had a couple left over boxes to burn up. I have a boat load of Palma 155 I plan on loading to shoot up also.

I've heard rumor of Armalites just needing round count to work themselves "loose". Also running them fairly "wet" is advised, im assuming the pop corn fart thing means you were pretty dry.

+1 on running wet. I've got two of them, & they both needed break-in that way. Both are reliable now. So far, a stuck ejector on the rifle & carbine each, and a bent extractor on the rifle at the 1200rd mark. I'm partial to the Armalite.

Thx. guys.

I was surprised how dry my rifle was out of the box. Hell, the receivers looked like white chalk and the inside , well Armalite must have been hit by high oil prices also....

The only things I have got accomplished was Armalite's suggested barrel break in and I did nip a coil off my ejector spring. My rifle was REALLY bouncing them off the receiver hard and tossing them WAY behind me.
