you can get what's called a CB cap.it is a 22 short lead with only about 1/3 the powder.it will kill a squirrel out to about 50'.at that distance it want go through a tin can.not alunium can,a tin can.
that way you don't have to worry bout hurting anyone.check them out.they look just like a 22 short,
so be careful and not mix them up.

Depends on what kind of pellot gun... You pump a sheridan too much and it will sound like a 12guage... hahaha

Just get a 22 magnum, there not very loud. hahah

cci .22 cb cap ... very very quite ..

The CB's are sweet i know "someone" who got a deer with one.

My next door neighbor shoots them out of his garden with .22 shotshells.I hear him every now and then when he shoots most of the time with those shotshells he just peppers them and they run but sometimes he can get close enough to kill one. Ive shot several out of my back yard with my .22 pellet gun and it does just fine but its just as load as my neighbors shotshells.
