A: Hi Walter! The 45 ACP could indeed kill America's largest game, but it's not the cartridge I'd want for defense against large bears, mountain lions, or belligerant moose or hogs. You'd want a hard cast bullet – and one incapable of expansion – so that you could inflict the deepest possible wound channel (thereby maximizing your chance of striking a vital organ). Look into Federal Solid Core, if you're able. If I could only recommend one round for dangerous game defense that we currently have in stock, it'd have to be this +P (i.e. extra powerful, and only suitable for firearms rated to handle its extra pressure) Xtreme Penetrator ammo by Underwood: https://www.luckygunner.com/45-acp-200-grain-p-xtreme-penetrator-underwood-20-rounds
