I built a 54 cal about a year ago, probably have 1000 rounds through her. I have run steel wool down the barrel about 200 times.Here's the problem.... I've noticed in the freshly fallen snow that my patches have holes in them around where the ball and patch touch the rifling. I'm using Walmart pillow ticking, measured at .020....washed and dried and a 4:1 ballistol lube. I tried some pillow ticking from quilt store the lady said her's was a tighter weave. Gave it a try.. didn't blow as bad but still had small holes.I measured the wallmart pillow ticking again this morning and it was .020 I've coned the barrel and this combo does not require a short starter. At 25 yrds the groups off hand are 1 inch apart. Do I need thicker patching? A friend suggested that I use cotton drill as it is a tighter weave. I've never had this problem before. Help guys!!!!
