If you live in a town/city/ sub division ect.... use a pellet gun! I think I speak for most people when I say "I dont wanna be accidently shot by you while eating breakfast in my kitchen" What goes up must come down and that means holes in roofs, cars, people ect.. and when you shoot at a squirrel most of the time your shooting in an upward direction. So for everyones safety stick to a pellet gun its just as deadly to a squirrel as a 22 short and trust me your neighbors will hear a short go off.
