Well I've read and read and read. Thought I did everything right and I'm still getting leading. Gun is a super blackhawk hunter. I slugged the cylinder at .432 so I sized at .432 powder coat. Loading in a 44 Russian case 240gn Lee mold. Loading 4.6gns of unique. I'm still getting minor leading in the forcing come. This sucks I've got a lot of money wrapped up in this to not be able to shoot them
