I have been using the Speer plastic bullets with the Speer plastic cases for years . Cardboard box filled with old newspaper is my trap .
It's the least hassle...I first tried wax and brass cases with the flash holes drilled out but find Speer's plastic ammo so much easier to assemble . I have bought extra bullets, shoot until I run out/low then empty the box and start over .
Very clean . Don't shoot any person or animal with one they will break the skin and you can put an eye out with the thing .
