The Schofield will load with 45Colt dies except for the crimp station. Get a 45 Scofield crimp die and you're in. You'll have to reset the bullet seater deeper. The Henry, 66 and 73 all use the cartridge in the lifter as a stop for the magazine, which means the round has to be the length of a factory standard round, as the Schofield is shorter, the rear of the next cartridge ahead in the magazine will go into the lifter as well and bind it from lifting. For instance, Cimarron sells a 73 in 44 Special, which will feed 44 Colt, with a longer bullet seated to the 44 Special overall length, but not the 44 Russian, which can't be made long enough, as the 45 Schofield can't be loaded to a long enough overall length. Boy, would that possibility increase the magazine capacity. Something to look at would be whether it's possible to modify or replace the lifter with one that would be the right internal dimensions for the 45 Schofield. If you had a second lifter that would work that way, you could swap out lifters to recalibrate the rifle.
