It all depends on how good of a shot you are. You can kill most anything with a 22cal shot placed right. Many of coons, possums, foxes, etc. have had their last hreath prior to a 22 round coming through their head. you can even get bird/snake shot for a 22. That is similar to a shot gun shell. It also dpends on how discrete you want to be. A 22 is often quieter than a fire cracker wne it is discharged.
The bottom line is what ever gun you choose you must be comfortable and confident with it!
