Re: surplus ammo?
The South African works very well in FAL's, M1A's, and just shot some the other day in an LWRC Repr, and it shot very well, just over 1-moa. Recoil was mild, if not weak since we had some failures shooting suppressed, but once we moved the gas plug to suppressed, the rifle ran 100%.
FYI, the bullet jackets are a lttle soft, and noticed it caused more copper fouling then normal in the M1A. Also it's Berdan primed so you can't reload those cases.
