Seriously considering acquiring an antique High Wall in 40-70 Ballard. Question is, reloading for this obsolete cartridge. Bullet molds and reloading dies are available for the 40-70 Ballard, but there is no correct brass. The "Handloader's Manual Of Cartridge Conversions" has some suggestions, but none that I like. I found an old post from several years ago on another forum, that suggests using the .405 Winchester cases, and these seem to have the closest rim diameter to the original 40-70 Ballard, .543 vs. .555. Load data is no problem as there is plenty of info out there on the 40-70 S.S.
Anyone heard of any 40-70 Ballard brass being available out there in cyberspace?
