I am brand new to the forum but not to guns. Just bought a REM 597 Heavy barrel 22 WMR from a friend but cant seem to find any HIGH CAPACITY magazines for it... seem to be plenty for the 22LR but not for the Magnum. It is truly a pain in the butt to change out 8 round magazines all of the time. Target shooting and squirrel hunts are always more fun with 20 or 30 round clip. Does anyone have advice/ answer for this...?
