an acqaintance at local range really touts vv133. It seems to have too fast burn rate to work. What do you think? does anyone have a pet load that they like for vv133? thanks/ chaz

You're right. V V 133 is a little fast for the BR. It's ideally suited to the PPC. It will work in the BR, as will all powders in that burning range, but V V 135 is a lot better. Now if you shorten the BR back to say, 1.1 or 1.2 inches then you have something. But since you already have the PPC why bother?

thanks/ i had already tried vv135 & didnt get great results. did shoot some varget with berger80's yesterday & the group was decent. my friend gave be one lb of the 133, so i am hoping to avoid the old "throw spagetti at the wall & see what sticks". if anyone has a load suggestion for vv133, I'd appreciate it/ chaz

I've never used V V 133 in a BR but if I wanted to I suppose I'd start with a max load for 6PPC and go up from there.

The 2000 Vihta Vuori manual lists 29.2 grains as max for a 70 grain bullet in 6mm BR Norma for 3104 fps. That's the only load it shows for 133.

Might want to try this site www.6BR.com they have alot of good loading data.

First bench test loads//VV133, 27.5, CCI BR4, Lapua brass, 68 Barts-1/2 inch 3 shot gp edge to edge/ 28.4 was 3/8 inch edge to edge/ 28.7 was 1/4 edge to edge. guess vv133 does ok with the light bullet.
