Plating is another rabbit hole that I’ll just spectate. I have quite enough rabbit holes to visit without help. I learned about nickel not plating well over copper when I played with shotguns. Plated shot for hard to kill birds is common and nickel plated was thought best for a time, if not still. Home made shot and people that do stuff for themselves, like we do, spoke of the better penetration of nickel over copper plated shot. Ford/Chevy maybe? But they wound up talking about the nickel had to be done over copper causing even more processes to be done. II knew right then that I’d be buying mine.
I’ve used some chrome looking heads in the past with good results. Have fun fooling with it.
