Do NOT use solid FMJ ammo for hunting, not effective or ethical.
Hollowpoint is no good. Its not really made for hunting, and what happens is your jacket separates from the core, and theres no real expansion, let alone reliable expansion.
A good Soft point is the way to go for a 7.62x39. A couple of good manufacturers make them. Dont get the wolf or tula stuff.
Good Luck Hunting!
