I have used BH in all my guns no problem at the range. I also have seperate breech plugs for each gun marked for BH use only. I am first a bow hunter but the smoke poles come out a few days a year. So shooting is done for fun and swabbing is not a issue. My hunting loads used in all my guns is 777 loose-dont have to worry about ignition problems(which no one brought up). One powder that had a very nice write up in PETERSON'S was Alliant Black MZ. Once i find some i will be testing it soon. I was wondering if anyone else read the article.
