I have a MK V that I want to reload for. I also have some 265 gr hard cast bullets in 455. From what I understand these would not be good for black powder use. However, I was thinking of using these castings with 3.1 gr of Red Dot. Is this a combination that is ok or should I try and get so soft casts? If it is ok, what would be a good bullet lube? Where too can I get some soft casts as I would like to make some bp loads?
