Last Dollar:
Buffalo Arms lists dies, but is out of stock. They list a cartridge case for a 500-.450 No. 1 Carbine, which I'm not sure is the same cartridge, but might be. I will try them and see if they know for sure.
Der Ami:
Thanks, but I don' think the 50-140 will be a good starting point.
The .450 No. 1 Musket is not the .450 No. 1 cartridge that I believe you are thinking about. It's an early 500-.450 cartridge with a case less than 2 inches long and shooting a lead bullet in the 260-270 grain range. An early deer rifle.
.50-70 might work, but I'd need forming and sizing dies and I'm trying to avoid that if I can find an alternative that lets me just neck size and reload.
