We had a Sharps 3-1/4" that would not shoot anything but
masking tape wrapped 400gr. PURE lead bullets. Go figure.

I guess what I am saying is straight paper is not the only thing you can patch with.

Mine, however, loved the 580gr. PURE lead conicals, 2-wraps
of .003" bond paper, with it's 18" twist - the longer bullet pictured in the above mould picture.
