Here is the latest update. I tried a lighter load with 55g Blue Dot, but saw no difference from previous. I went back to 60g Blue Dot and cast a heavier pure lead bullet. I also adjusted the wad column. I also changed from lathe turned brass to Parker brass. The lathe turned brass had a thick lower wall with a reduced powder chamber. This produced higher pressure and required severe resizing after the first loading. The thin wall Parker brass seems much stronger and required no resizing even after 3 loading. I am very happy with these results and will move out to 50 yards at the next outing. I also received my Tanner .875 dia round ball mold and will be testing it also.
