What powder is the most temperature sensitive, Varget, VV540, RL15 and in what order?
Thanks,Art

Art,

My opinion from the most temperature sensitive to the least temperature sensitive would be:

VV540 most

Reloader 15

Varget least

If your looking for a powder to shoot all year long without having to play with the loads too much it's pretty hard to beat Varget.

Cant comment on the 540,,as it is one of the handful of powders I don't have ) but in a side by side comparison in my 308, the rl15 dropped about 2x the fps that varget did with a 20-30deg temp drop.

comparison was only done once, and only with 5-shot groups, so YMMV,

Looks like it's Varget. All three powders shoot well in my new 6mmBR. And I'v never had a 6BR before. And as dreever said I don't want to play around with the loads much after I get a good load worked up.
Thanks dreever and jb1000br for the info. Art
