Hmmm, lowest bidder for ammo down the road like every Government contract. Sounds like fun getting a stuck case out when the head rips off.
I have LR-308 pattern rifles and AR-15 pattern rifles chambered in the same wildcats for deer hunting. The AR10 hasn't been out in 3-4 years. A step up from 5.56 would be nice, but IDK if this is the right move.
