I have been trying to get into the reloading scene being I am no longer allowed to play with my explosives (retired). Started loading some 9mm rounds using a Lyman turret press and Lee dies (factory crimp). I am using IMR SR4756 (4.5 gr) and 125 grain round nose lead. My issue is when I fire them through my Tokarov I can shoot 15 to 19 rounds and then my weapon will not go into battery. I know it is probably a lead issue but does anyone know what else I can do to help this along?
