Do we know what Buffalo Arms is making their 56-50 cases from? I would assume it could be 50-70 or 348 Winchester. Are there any other cases that this case forming operation could start from?
Also would the reloading dies themselves, the actual dies, have to be different if using brass formed from 50-70 and compared to 348 Winchester?
Finally it would seem as if there could be three types of 56-50 brass. I'm not talking about guns firing the original cartridges as opposed to the replicas but rather just within the replicas themselves. If you were only considering Taylor 56-50 guns, couldn't you have three potential types of brass, namely brass specifically made for these guns as Starline is doing, brass formed for these guns that started life as some other case as I assume Buffalo Arms is doing and brass machined from brass rods as Rocky Mountain Cartridge is doing. Could these three sources all work with, say, one set of Lyman dies?
