first off. check your regs. not all those animalsare in right now. And at least here in ohio, if you just start shooting beaver, you'll get in trouble haha. That being said. the .22 is your best bet for smaller game. squirrel rabbit coon things like that. Ive even taken a few 'yotes with a .22lr. Not recommended tho. the .17 is good for groundhog, crow, 'yotes, any other nuisance animals. Just get out there and have fun, make sure your legal tho.

For dressing. make a cut at the back of the animal, put your fingers in and pull the skin off. cut the legs and head off once the skin is pulled that far. Than make a cut over the stomach skin, (dont punch a hole in the guts) long enough to get your fingers in and pull it all out. then soak the cleaned meat in slat water and cook or freeze, yuour ready for some good eating!
