    This is the only powder I could find within 150 miles of my house. I have seen some load data for my 300WSM but I can not find any info on how temperature sensitive it is. Can anyone help me with this?

    I have used it in a 300 SAUM and found it made little or no diff. in POI out to 200 yards, only distance tested. This was for northern Mn. deer hunting with 180 gr. bullets.

    If is the only powder you can find buy some and test it yourself. You do not say what the temp diffs you will be shooting are so it is hard to say and shooting distance also is important, long matters and short not so much.

    PS I developed the loads at 80 degrees and confirmed them in the 20's.
