Well, I am glad to say I think I've found 5744 works out well after all in my 45-70. After so many have spoken of its excellent fit with the cartridge, finding it disappointing in my own guide gun, I'd pretty much concluded my gun prefers I 4198 and moved forward with a hot load there.
Whatever happened previously, whether it was poor sorting on my cast 405's, lube issue, whatever it was, pleased to report. These are only 4 shot strings so nothing to conclude until I do larger strings but still, I'd be pleased with any of these loads and invite your thoughts:
