I have been working on a load that works with my pedersoli SxS 12. I loaded 1 1/8 number 6 lead 60 Grains but had donut in middle. Today I made some paper patch 1 3/4 oz shot, pushing it with 70,75,80 2f black powder. all shots were at 35 yards. 2 inch red dot. 14 inch circle. the barrels are extra full and 2 extra full , which makes them hard to load. Do you think this is a good enough pattern?
