CCI Minimag has been my go to ammo for all my 22 rimfires. It is the most reliable firing ammo that I have. It is not the most accurate, nor is it the worst. It is the only ammo that will fire 100% reliably in my Walther P22. I can't say that for any other ammo that I have tried. I don't recall it every failing to fire (or to feed properly in autos).
