I've just developed a hankering for a 20 gauge rifle, after reading the article in the Autumn DGJ. What I have in mind is to get an accessory rifled 20 gauge barrel for my New England Firearms single shot break-open rifle. I know that I could just use rifled slugs, but I'd prefer to load my own and use paper or brass cases and cast lead conical bullets, probably paper-patched, and load it like a rifle. I may use black powder and smokeless as well. I'd like to hear inputs about cases, bullets, wads, powder, reloading dies and loading data. Will the thin Magtech brass cases work, or are there thick-walled brass cases available?
