I've got some 230 gr HST bullets fired through water jugs that look awesome with the full mushroom shape and sharp edges. But I've got some fired through wood that didn't open and penetrated way past the 3 water jug length. Gold dots did the same.
Speed kills and things moving around 3000 fps are a pretty safe bet.
The Colt 9mm carbine I had was a fun toy but nothing else.
Grab some sheet rock, wood and water jugs and see where you want to place your bet.
