I use Federal Crimped .22 Bird shot it works fine in my auto Ruger and my conversion kit for my CZ75. The ones that have the plastic cap will not work in my guns.
Ask any little old lady in the south. They'll tell ya the best snake killer is a garden hoe. My Granny was snake killing machine with that garden hoe! If I were you I would go buy a Ruger Single Six. I have killed a lot of Rattlers in my younger days with the CCI shotshells. They just curled up and died, very little thrashing around.
Why not a decoy retrieving pole? They have the same style hook that people use to pick up snakes and put them in sacks.
