I have used a Beretta 92FS, Mossberg 500 riot, AR-15, S&W 686P, 1911, Sig Sauer P238, Ruger Mark III (Bull barrel and Hunter Variants), M1 Garand, Ruger 10/22, Winchester 190, and a few really old 22s handed down through my family.
I was given the opportunity to use a Marlin 1895 in 45-70, and the infamous S&W 500 Magnum. I turned these down for obvious reasons.
