[:'(]Dont shoot a .223 in the air at a squirrel!!!!!!!!!!!!!!!!!!![:@]You miss you could kill someone a mile away.!.!.!.!!!! The best thing to do is to get either a .22 long rifle, perfered ruger 10/22, or a shotgun, perfered 410 with a full choke and 7 1/2 shot. Those make one heck of a squirrel gun.
