When I was in (early 80's USMC) we were shooting Viet Nam era A1's. We kept them clean and they went bang. We were also able to hit man sized targets at 600 with them, off the freaking rack.
The only problem I have with what's being issued is the ammo. That bullet sucks. It should be a soft point.
Well, there are SOME advantages to being a civilian now. We don’t have free unlimited ball ammo, but we can buy mean and NASTY ammo!!!!
