7mm rem which vv powder for 140&160gr?

[elmerdeer]

I have been working with rl22 andthe 140gr ab, and the rl22 is very temperature sensitive, my loads 66.5 gr room temp from car av speed 3020fps, 20 min-30 min later same load av speed 2850fps. I was expecting a loss but thats to much, so I'm looking for a powder thats less sensitive to temp change and I've heard that Vihtavuori is more consistent, so which one should I get?
Thanks
Elmer

N560 is the best for speed, at least in my Rem700. But N160, N165 and N170 work very well too, N160 for the lighter, N170 for the heavy bullets. I have no experience with other powders than Vihtavuori, maybe due to the 60 miles to the Lapua powder plant...

I have been very happy with Retumbo.....

+1 on retumbo. It's also Walt berger's favorite.
