I’m going to try VihtaVuory powders for the first time and will be using it to load 9mm and maybe .44mag (I’ve used a number of Hogdon, Aliant and IMR powders already)…
I was wondering between 3N37, N350, N340 which powder produces the largest muzzle flash?
Aare they grain or flake powder? Also do they measure consistently thu something like LEE auto disk? And are they clean burning?
