Home Forums Hunting & Shooting Ask The Gunwriters Ask John Barsness Questions About "The .300 Weatherby"

John,
As far as powders for the 180 to 200 gr. bullets, which would you say are the least temperature sensitive? Right now I am working with IMR-7828 SSC and 180 bullets, trying to work up a good load for my latest acquisition. The rifle seems to like this powder. I was wondering how this powder rated for temperature insensitivity, or if there were better choices.

Thanks for your help,
Steve
