I bought my old T/C Renegade years ago, used. I have shot a number of conicals and patched ball with varying degrees of accuracy, and have only cleaned it by scrubbing with a brush and boiling water or T/C No. 13 cleaner. Could there still be original lead that I'm not getting off, and worth hitting with a lead remover?

I've seen bores get leadded up from using maxi balls for many years; but not an occasional hundred or two. Couldn't hurt though.
