>>210758Dis one mine. I made it. Steel ball bearings as ammo. I take it with me all the time. I've gotten squirrels, rabbits, groundhogs. Basically anything I want. It will put a ball bearing through 3/4 inch plywood so, I imagine larger animals from close range and headshot would bring them down. The problem would be stalking up to a deer from behind and making a headshot from 30+ feet. Theoretically possible, practically very very difficult.
