Re: 45-80 Expieremental Trapdoor

Hi Dan, The .45-80 cartridge was originally intended for use in the Long Range Springfield Rifles for use by the Army competitors at the Creedmore matches in about 1881. The bullet of this round was 500 grains in weight, paper patched, and seated very shallow in the case. The case was 2.4" long and held 80 grains of black powder. This particular cartridge led to the development and adoption of the M-1882 rifle cartridge. The M-1882 had the 500 grain bullet with cannelures (grease grooves), and the 2.1" copper case that held 70 grains of black. Experimentation between the .45/80/500 and the .45/70/500 showed little appreciable difference between the two. I hope this has helped you out some. Regards, Ken
