The balloon head Schofield rim of the day was not a great deal larger than the balloon head short and long Colt round of the same period, but it was .018" larger +/- .003" due to manuf. tolerances when measuring the balloon head 45 Colt, 45 short Colt and balloon head Schofield rounds in my collection, clearly not the same and enough to make a difference. Also enough to require different shell holders in most brands of reloading tools when I reload them.

The headstamps of the Remington short 45 Colt and the 45 Schofield were always different to delineate their lack interchangeability in S&W revolvers. Also, recognize that the Remington “short” 45 Colt round is not a Remington version of the 45 Schofield because it has a thick rim like the 45 Colt and will not chamber in S&W Schofield revolvers.

Actually the difference between modern solid head 45 Colt rims and modern solid head Schofield rims is less at a measured difference of .010" +/- . The solid head 45 Colt having evolved to a larger rim.

Yes, the ".45 Caliber Ball Cartridge, Model of 1909," was the other cartridge specifically designed with a larger rim similar to the Schofield for more reliable extraction in DA revolvers.
