Never got the accuracy out of Varget I hoped for in my .280 rem, but I blame it on the compatible bullets for my 7400. It seems to love 150gr range and not like anything else, not even a little bit, for accuracy.
Well, I couldn't find IMR 3031 but I have 8 lbs of benchmark and I'm pretty happy w/ it in everything else. Since they're close on the burn chart, I'm going to 'speriment. Now according to my math:
in 30-06, starting load for a 150gr bullet w/ IMR3031 is 43 grains and with b'mark it's 45 grains +/-depending on the bullet profile.
SO, that means benchmark is by-volume of powder less pressure than the 3031.
Acknowledging that the slightly smaller 7mm bore of the .280 will produce higher pressure, I think if I start working up the benchmark at 40 grains (better safe than sorry- worst it can do is not cycle the girl) then, I might be able to find a load that works.
The idea of benchmark's all-temp accuracy appeals to me because deer season is cool, hog "season" is warm, and coyotes season is crazy.
