I carry a tauruspt22 with Stinger lr rounds. i hear all the talk about 22 rimfire duds,however , i must have shot at least 5000 rds of cci mini-mags in addittion to the stingers and never have had even one failure to fire,?? because i can afford to shoot every day and i do, i hit what i aim at with my taurus i feel very confident in my ccw 2245
