I like the catch 22 cartridge holder. I primarily use mine for holding rounds in my pack, and it would only hold about 3 reloads for a marlin nodel 60, but it is so much easier to carry than arrows full of cartridges. My primary 22s are a marlin single shot bolt action, a walther p22, and a ruger 10/22, in that order. The catch 22 is nice for separating different rounds, as i always keep a few CB caps around for use around the homestead, which is why i like the single shot.
