Midway sent me an email that Vihtavuori N540 is in stock. I bought a couple of pounds to try out, since not much else is available. Yes, it's high as a cat's back. Lol
I bought because it's marketed as a versatile powder, since Varget and 4350 varieties are scarce, for loading 223 Rem, 6.5CM and 30-06. I haven't had to use it, yet. Hopefully it will be as versatile, as Vihtavuori claims. I've bough a variety of powder, over the past six months, just because it's scarce.
