I used Hevi-shot Duck in my 2 3/4" A-5 this year and liked it a lot better than steel. However, Hevi-shot Duck is "watered down" at 9.7 g/cc and I'm thinking about loading my own genuine 12 g/cc Hevi-shot next season. I've loaded many rifle and handgun cartridges over the years, but have never loaded my own shotshells. How challenging and how much of a hassle would it be for me to start out loading Hevi-shot as opposed to lead? Thanks.
