Howdy, I've a marlin 22 mag SS rifle, clip fed, synthetic stock that shoots great after I honed the trigger & free floated the barrel. It will shoot 3/8" groups at 25 yards with CCI maxi mags HP & Federal premiums. With other 22 mag ammo it shoot 1" at 25 yards. Try different ammo before you give up. Any questions, give me a pm or email. Good shootin!
