.22 Winchester Rim-Fire, a shorter and weaker (but same diameter) alternative to the .22 Win. MAGNUM Rimfire, is available again. It looks like CCI made a batch of it recently. It's available at Foxhole Gun & Archery in Gainesville. This is good ammo for you folks that are just getting used to your 22 Magnum derringers and mini revolvers, but don't have a convertible cylinder to shoot 22 Long Rifle out of them. And if do you want to train a kid in shooting a 22 magnum gun, this stuff is quieter and may be more user-friendly for the first couple range sessions.
