So I found a local provider that is supposed to be getting Vihtavouri powder in stock. And at a decent price I think. About $50/pound. From what I am seeing, the N570 is being in a lot of the Magnums. (7mm Rem, 300 WM , 300 PRC) If that is a wrong assumption someone please correct me. I have two questions here. How is the temperature stability? And how is it comparing to H100 and Retumbo? I already have these 2 powders but want to explore all options for the PRC build. Thanks for the help everyone.
