I have been loading for an original Springfield Trapdoor for some time: holy black or Black MZ and 405 or 500 grain cast like the old days. But I ordered a Uberti reproduction of the 1885 Winchester Highwall, and am going to add a "modern" load for it. Bullets, of course, are an issue. Hornady 300 gr HP (#4500) are backordered. Beggars can't be choosers.
I would welcome other bullet suggestions, but my main question is powder. Hornady tested typical fast powders, and I do have H4198 and IMR-4198 on hand. Speer tested these also, but they added some medium rate powders, specifically IMR-4320, of which I have a good supply. What are you using?
