I have trapped or otherwise dispatched a lot of them over the years in horse barns where they nest in the hay and get into cat food, trash cans etc. and make a horrible mess. They are on par with possum. I'm not a fan of either one growling/hissing at me in a dark haymow. The are about the most unpredictable animal you will encounter as far killing them goes. Some just flop over and die, some seem to be hyped up on PCP and just keep going, it can be a bit disturbing.
A .22 pellet in the right place will kill them as fast as a 9mm jhp but shot placement is not as forgiving. Body shots of any kind don't seem to slow them down much, they will die, just not quickly. I have pretty much settled on shooting them in traps with a .22wmr revolver using CCI ballistic tip loads. The frangible bullet is safer for me if a shot hits the trap, and it does a lot of damage to them. I generally put the first shot in their head, and put a second shot in the boiler room for insurance as I don't like watching them flop around and fighting any longer than necessary.
I wish they would just stay out in the woods where they belong, but this spring and summer they've been after the neighbors chickens and also into everything in the horse barn. In the barn office they open a one way cat door, get into the office, open a cabinet, drag out a plastic bucket with a lid and dump the cat food on the floor for a feast. I think at least half the neighbors chickens are dead as well.
