I don't follow what you are saying there. I competed with a single shot .22 rim fire target pistol up to a few years ago when I sold it on. I could get one again with the relevant variation to my FAC.Same reason you can own a .44 muzzle loading revolver or a box fed 12 bore semi auto assault shotgun but can’t own a single shot .22 rim fire target pistol
Cause politicians are ****s
