My ML shoots better off a fouled bore for me. After I check my sights/scope before the season, I give them a thurough cleaning. I too then fire a squib load of 30g of tripple 7 and a cotton patch, followed by a field cleaning of a spit patch and a few dry patches. Now I can load and go hunting. Durring the season I will clean my ML occasionaly after several rounds have been put down the tube. Before I hunt I always use my squib load/field clean/go hunt pattern.
