25-20 S.s.
If you can do a straight centerfire conversion, you might try trimmed 25-20 Single Shot cartridges, or 32 Short Colts from Huntington Specialties. I think someone online advertises these with offset 4mm rimfire blanks for primers. But obviously, centerfire is probably the best route if your rifle will stand it. Remember, black or 777, replica powder only. The colt 32 bullet is right on, if you can find these little slugs for reloading. Ammo-one.com had some of the Navy Arms ammo for collectors, but they're about $75/50.
