with varying success. I've also used smokeless loads. In the case of .45-70, one of the recommended propellants is Accurate 5744. I like it, because I can get groups like this at 200
when I do my part. Which, at times, makes me wonder if I should keep screwing with black.
I will, because I've gotten some quite good results a couple of times, but it's nice to know that if I need some accurate ammo that doesn't require compression and other fiddling, A5744 is waiting.
