I've used a number of .22 rimfire rifles for the purpose, Belgian Browning, 10-22 and a Remington 512 -T come to mind. S&W Kit Gun, K-22, 317. Probably if I had a favorite it would be my old model Ruger Single Six (Which I haven't seen in several years because it's suffered the same fate as my SP-101: my brother really likes it. You know how it is with brothers.)
