We all know rimfire isn't the most reliable form of firearm cartrige, but I'm curious what others have found to be the best, based on their experience. I know some guns prefer some ammo that others wont fire, and visa versa, but is there a brand/type that seems to suit them all, or perform better on an overall basis? ...thus the point of my inquiry. In three of the four 22lr guns I've had, CCI MiniMags have performed flawlessly. However, one doesn't seem to like anything CCI that I've tried (MiniMags & Blazer bulk). When presented in another thread here, someone suggested that this is because CCI tends to make harder to strike/ignite primers. I'm not so sure about that, but I can see the possibility of it with my aforementioned experience. Anyway, I've yet to try anything else, but just picked up a box of Federal bulk to do so next outing. Hoping for better contact with the picky piece!! Wish me luck, am looking forward to the findings and experiences of others. Thanks all!
