IMO there shouldn't be a break in period on an AR10. Clean & lube the BCG. Make certain there's a bit of oil on the firing pin, and that the firing pin goes all the way forward. Meaning that it can really dent a case. It's possible that there's some gunk that doesn't allow the firing pin to move all the way forward. You can check & clean the chamber, although I wouldn't bet that's the root cause.

I've heard people state that some military primers are really hard, which can lead to light strikes. I don't know if that applies to the ammo you used.

I know nothing of BRO triggers. I have a Wilson Combat single stage in mine -- it is outstanding.

The legs should be on top, not on the bottom.
