Just picked up a 1866 dated Trapdoor Springfield Rifle (three band, not cut down).
I've have brass and dies on hand, with a Lee .515 diameter, 450 grain bullet mold inbound.
All I need now is some load data.
I hope to use Accurate Arms' 5744 powder.
Anyone have load data?
There is nothing on the Accurate Arms web site for the 50-70 cartridge.
