I think your gun would benefit by polishing the inside of the barrel. A smooth barrel picks up less lead, and is easier to clean, too. The tools for lapping a barrel are not very expensive and it takes only a little while longer than removing a bunch of lead. Firelapping is easier, but it seems too easy. There's gotta be a catch.Jayhawkhuntclub":rw4l394d said:The problem is I'm having trouble with leading. It leads everywhere from 6.0 to 9.0 gr of Unique. It gets a little better when I drop down to 6.0 gr and real bad at 9.0 gr. These were supposed to have a BN of 15. That seems unlikely to me. Seems like I would find a spot where the leading would minimize without dropping below a starting load. What do you think?
