I would not recommend a 22. I use the most powerful handgun load I can manage. This is not a job to do feebly. You want to be thorough and deliberate about it.

The toughest so far was a horse. You'd be surprised how emotionally compelling a very pregnant young woman can be. Not something I care to repeat. Thank God I was only assisting the Vet that time. Brutal memories, but we did the best job she could've asked for.
