Thinking about finally trying htl shells. Ill be shooting them out of a brand new ithaca turkeyslayer with a rhino choke. Has anyone had any barrel scratching or scoring using hevi 13? I know the shot is much harder than the barrel steel, or thats what i have heard anyway. Just dont want to scratch up the barrel of my new gun. Lead works well for me, but I SURE DO LOVE OVERKILL.
