I am looking for all the rimfire rifles that use the same magazine as a .22 pistol or vice versa, so far the only ones seem to be the walther p22/g22 and the buckmark with the rather odd (and pricey) buckmark carbine. Has anyone ever made a rifle using the ruger 22/45 magazine or a pistol using a marlin rifle magazine? May seem stupid but I have a Marlin camp 9 and several pistols that use the same mag it just seems to make everything simpler. Thanks
