Thread: Military Surplus

I wouldn't bother mucking around with modifying FMJ for hunting. Even if the jacket is copper (which is unlikely) it won't expand much at 7.62x39 velocities. Even the norinco soft point stuff available a few years back drilled straight through animals. It does work when drilling out copper jacketed 308 projectiles, but you have to drill at least a 1/8" hole 1/4" deep to get much expansion even at 2800 fps muzzle velocity. I suspect you would almost have to cut off the whole front half of a 7.62x39 to get much expansion on game. The jackets on FMJ projectiles are very thick. Unlike hunting SP ones.
