I've scouted this forum for about a year attempting to find a cure for misfires in my 30-30 Handy(50% misfires). I tried all the suggestions offered to others with similar problems. but never posted. I put the rifle away for about six months, then I cured the misfire problem yesterday by swapping hammers with a NEF shotgun. Why it helped I have no idea, but now the new problem. When the barrel is level or directed down the hammer will not cock, if I raise the barrel to about 20 degrees above level the hammer cocks easly. When I hold the rifle level , but up side down. It will cock untill the barrel is directed down about 30 degrees. Can anyone help? and any idea why the hammer swap help with the misfires.
