I can't think of a more American way of killing flies than shooting them with a gun. I created this object to help reload salt rounds for either the Bug-A-Salt Shred-Er, or Crosman Vigilante. Simply snap it onto the back of the pellet clip, fill with salt (I use a blend of 4:1 salt to cornstarch), and then add one drop of water to each chamber. Set it aside, let it dry, and then you are good to go. It works great.
