Vihtavuori, anyone?

[youngun]

Is this good stuff?
I hear it's clean.
Where can you get it?

I'm looking to load 230 gr .45's @ 900 fps +/-.

Thanks for the help.

It is probably the best powder out there. Very expensive.

Here but you have to buy it in volume:

BTW one of my friends just started a firearms link index website. Check it out. The site is still undercontruction but once finish it will contain a large amount of firearms informations.

Here is the load data from Vihtavuori themselves. The Europeans load hotter then us. So it is a good idea to drop the load by at least 10% and work your way up.

Highly recommend Alliant Power Pistol when chasing high velocity in the 45............and IMI cases.
