At one time, I had an empty baloon head case. It was nickel plated, had no extracter groove, was schofield length with a very small rim. The headstamp said .45Colt. Keith said in Sixguns, these rnds were quite inferior to the longer Colt rnds with 40gr of black powder.
Just to put some numbers on .45 rim diameters, I checked information in Hackley, Woodin, and Scranton's book on U. S. military cartridges. They provide no dimensional information on the early inside-primed .45 Colt and .45 Schofield cartridges. The first reloadable Boxer-primed copper cased .45 Schofield round (the M1882) had a 0.524" nominal diameter rim. Due to manufacturing tolerances, there was apparently some difficulty experienced in rim interference in the Colt SAA revolver. Therefore, in 1887 the rim diameter was ordered to be reduced to 0.513" nominal (0.510"-0.516" tolerance). And there it stayed. The final rim diameter of the M1909 cartridge was 0.536" nominal. The current .45 Colt has a rim diameter of 0.512"
