Im not a big fan of match grade ammo. My interest is top shelf quality ammo that shoots,goes bang in any type of weather. I find that CCI surpasses most of the other brands of rim fire in this category . Frozen, cold, damp, nasty conditions CCI has been more reliable in my tests. However even CCI has failed me one time. I have never had a centerfire dud in any caliber. I have had a bad firing pin in an old bolt action 30-40 Krag but never dud shells. Bulk pack .22 rim fire has proved to me to be only good for hunting or target shooting.
