Do y'all think I'd be ok using Federal 5.56 m193 ball ammo in my .223 savage 12fv? I had 2 boxes, they're in good shape, and when I got them, the boxes were sealed (no mismatched rounds). For shooting at the range, would these be ok? The rifle is unmodified, and I've shot 2 bullets from it, I bought it new. Thanks in advance
