men, small deer,shtf foraging, practice, 30 AK for suppressed,subsonic work,or big deer, 308 for sensible big game-taking, 300 Mag for showing off at long ranges, stopping big animal charges, by virtue of BAR'S rapidfire. Me,I'd just skip the 300 Mag, use the 308, take head shots at the big critters. Given Barnes "solids" in 30 cal, even elephant would be no big deal. With the cheap surplus ammo, you could get in lots of practice,hitting the football sized brain circle, swiftly and repeatedly. Elephants aint that fast. 30 fps in full charge.So if you fire at 30m, and the earhole shot doesn't drop him, you have 3 seconds in which to switch to the frontal brain shot, before he can reach you. that is time enough for you to take another 4-5 shots, carefully aimed at the brain. That suffices rather nicely. In fact,it BEATS the 2 tries that abolt 375 user gets, in the same time,by 100%.
