Vihtavuori was not available locally, way back when you could actually buy powder.
If I had my druthers, I'd buy a pound or two of W231. It seems to be the 'broad spectrum' powder for the pistols I reload for (bullet makers all have loads for it).
In the past, I would settle on a specific bullet and then try different powders, different charges, until I hit on the 'sweet spot' for that pistol. Now, I just want a load/bullet that will cycle the action. My days of 'Expert Marksman' badges are over. I don't even care about the 10-ring anymore. Hitting paper is good enough.
