hits to chest, from side, before either could run 100m. One only made it 50m, before staggering, going down, back legs first. Big buck, too. 170 gr 30-30 sp OFTEN does no better, and SOMETIMES 308 sp doesn't do much, if any better. 308 BALL does no better, either. . It's feasible to can a shorty 223, it's NOT feasible to can an M1A. The result is just too heavy and awkward a rifle.
