Thanks for the info on the vihtavuori powder acloco. I've never tryed any of there powder befor. And right now i'm playing around with benchmark powder to see what i can come up with for accuracy. But i might try it latter on some time. Thanks agine for puting up here for every one.

Hmmmmm, I used to shoot IPSC against Don Alphabetski, way back when. I haven't done that in years, though. Didn't know where he'd turn up. Cool!

Hmmnnn I thought maybe Viht had finally gotten its act together and done some testing. Quess not, that data sure looked familar and somewhat contradictive. A 32bk with N-140 is only good for 3700fps while a 32 V-Max can be pushed to 4200fps with the same powder?

It seems Viht is just pushing around data made by Sierra and Hornady. I do not have Walts data on hand to check but the Berger data is probably from him. They could/should do better than that.
