I would shoot them out of a Contender, Browning Micro Medallion, or a Ruger #3 at paper targets with cast boolits.
I do need to cast some more with my NOE 225-48-SP mould. A member needed some to try out his new Handi Rifle, so I sent him what I had cast and some PPU brass since he had no brass!
Prairie dogs and other small game will be later!
