I am an idiot! The whole reason for re-boring was not because the rifling was not visable, but because I could not get a dry patch down and back out again.
A few days back I had spent the whole day fire lapping and hand lapping the barrel with the breech plug out. At the end of my session I ran enough dry patches through the bore to dry it, and then inspected it with my "eye". To me it did not look like I had accomplished anything. I did not bother to put the breech plug back in, and see if I could run a dry patch in and out. Well last night I did just that, and to my amazed eyes like a new one the dry patch went in and came back out along with about 20 others. I am really excited about this turn of events, this means tommorrow I can go to the range with some .36 cal balls and if she shoots, I am good to go. Some times its good just to have a place like this for a sounding board, it helps us nim-wits work things out as we are pounding them out on a key board.
