The worse I've seen has been a donut shaped patch, but it still had the groove marks on it. I'm trying to find some tight weave cotton .010 to .015 thick. Any thicker and I can't get the ball down the barrel. Have not tried any commerical patch material yet.
Side note, is Doc going to make the 54 double? How much would such a beast cost?
Thanks, Colorado
