raccoon and possum: .22 short to the head. a couple .22 holes make no difference on any pelt

fox: compression
bobcat: catchpole
coyote: either compression, or a .22 short behind the elbow
skunk: .22 behind elbow, or syringe ....if you shoot in the head they will spray

beaver, otter: dead on arrival. I did have to shoot an otter in the head once that was caught on a long chain, with a .22 short. Out like a light.

a .22 short is all that's ever needed. For long hair, fur out, it's best not to shoot because cleaning up blood is a big pita, and other methods are just as easy and humane. Shooting a coyote behind the elbow is faster and less messy than in the head.

If you want an explanation of any methods I discussed, shoot me a PM.
