22 magnum fan
I am a fan of the 22 Magnum. I have a Ruger Single Six that I shoot almost exclusively with 22WMR ammunition. I have two other 22LR revolvers and two 22LR semi-autos that are more accurate than the single six with the 22LR cylinder in it but the SS is very accurate with the 22WMR cylinder in it.
I would like to have one of those old AMT 22WMR semi-autos (and one of the similar 30 Carbine ones, as well) if I could find one for a reasonable price.
