60 gr bullet 9 gr 2400 1790 fps

86 gr factory load 1410
If it were mine I'd only shoot lead bullets in it.0 -

Do note that the .25-20 Single Shot is NOT the same as the .25-20 Winchester (WCF). The Single-Shot cartridge is significantly longer and has more case volume. Introduced in 1882, the blackpowder round was too long to work through the Winchester 1892 or Marlin Model 1894 rifles, so Winchester came up with heir shortened version.
Load data for the .25-20 WCF can probably be safely used in the larger SS case, since you'd want to keep pressures down anyway. Cartridges of the World #9 suggests 8.0 2400 or 8.5 4227 for about 1400 fps with 60 to 86-gr bullets.
Proper replacement cases might be very hard to find, but I'd bet that Huntington Die Specialties (not RCBS) would have some. http://www.huntingtons.com/cases.html0 -
