What works best for me is ballistol mixed 7:1 with water. Soak the patches and then let dry completely for a few days. I use 90 gr with a .490 ball and a.015 or or a .495 ball and a .010 patch.. Bore butter is a good patch lube I just get better accuracy with the "dry" patch of ballistol. Post some target pictures and we might be able to tell from the targets what might help
