I have a 22 marked Savage Sporter ( no suffix.) It has a magazine marked "23A Sporter or NRA match rifle". The S/N is 66?8?. Triple K advertises various magazines for some 23's, 19's NRA TARGETS etc. They are 10 cartridge mags. The one mag I have has been rode hard and put up wet. Has anyone used the Triple K in a Sporter? There has been some "customizing" on this rifle and this may not be the original magazine. It has checkering, a mirror polished floor plate, no schnoble or blac fore end tip.
