Hi, I have an 1873 TD that I`ve sportized & cut & recrowned the barrel to 24" There are pics of it on this TD section. I shoot Rem 405g .458dia JFNSP bullets out of it in front of 34g of Reloder 7 & it shoots fine. My problem is, I have bullets, brass, & primers, but no powder. I can`t find any . I`m old school, so I don`t want to try any other smokeless powders even if I could find any. BP powder is no problem for me, so could I use BP behind the jacketed bullets, & if so what load (grains) would you recomend? I know BP is measured in volume as I shoot C & B revolvers also. Would you advise putting a lubed wade between powder & bullet to keep fouling down? Thank you in advance OTD
