I had to switch my pistol powder due to supply issues. I'm switching from Win 231 to Vihtavuori N320. Powder is hard to come by but I think this 2 kg aka 30800 grains may get me through this powder famine.
Anyone else using Vihtavuori N320? PM me your pet loads for 9mm and 45 acp cast.
A quick video showing my thoughts and some of the powders characteristics.
