As to duplex loads, my best for the .50/70 was 10gr. of IMR3031 and 60gr. black, 2F I think.
In the past, I have used SR5759 in duplex loads, but that one with IMR3031 worked like a charm in an original model 68 Sharps
barrel and shot more cleanly than the lighter loads using faster burning powder. Standard primers.
I read about using IMR3031 in a handloader magazine, or perhaps it was mentioned in BP Ctg. magazine my bro gets.
Interesting, Daryl! I've used the faster powders with excellent results but have never heard or read of using IMR-3031. It's such a versatile powder I'm not surprised to read what you wrote. The SR-4759 load I mentioned shoots cleaner than some smokeless loads I have.
