I shot a Thompson Contender in 35 Remington, and it was pretty smooth shooting.
I Shot the 50AE Desert Eagle, that was fun.
Shot Many a 44magnum.
Shot a .357MAXIMUM, WOW!!! what power. 2000+ fps on a 158gr JHP
I got to shoot the 500 smith and wesson, it felt alot like the 44 magnum. I wasn't impressed.
I'd like to try a 454 casull, or the 460 S&W, they are both reported to be beasts.
