All, this seems to come up periodically so hopefully Dave will save it somewhere.
The brass can be made from 40-90 Sharps basic brass or from 30R Blaser brass. The head diameter is NOT the same as 9.3x74R. That said, you can use "thumper" brass if you are careful and aware of the 11.9 vs 12.1 mm head measurement difference and keep pressures low. A gunsmith friend shared his load with me which calls for 300 grain Hornady XTP pistol bullets. They work nicely in the "Baby 45-70" on all but elk or larger-sized animals. For those I use the 300 gr Swift A-frame pistol bullet. One of these loaded full-blower shot completely through 16 inches of wet phone books and half-way through a 50 lb bag of cracked corn and was found perfectly mushroomed. The 38 caliber XTP's are also very nice in the little 9.3 and much easier to get good groups from than lead; yet they are all soft enough for Henry-type rifling and still give good expansion. If you are leery about using this cartridge on game, consider that 11.15x65 ballistics outclass the .454 Casull by a good bit.
Pete, like many old BP German cartridges, the brass starts short (40mm) and goes on up to the full LK (LanKaster meaning shotgun in Duetche) 65mm Express. I think Dixon shows 5 or 6 variations. It was factory loaded by Utendoerffer, DWM and finally GECO up until WW2.
Good shooting,
C.
