[QUOTE="justgoto, post: 526169, member: 17125"] Yes. I used to use IMR 4831 in my 30-06. I would get a POI difference of more than 2 feet at 300 yards from the winter/summer temperature swings. With H 4831 I get maybe 3 inches. Nowadays, I don't even consider using temperature sensitive powders. To add... The last load I developed using H 4831 had a ES of 5fps. That's in a 30-06 using 180gr bullets; I don't know how well that translates to a 300Wby. [/QUOTE]
