[QUOTE="Korhil78, post: 3019280, member: 34818"] Mine is experience of using both powders living in the SW desert of New Mexico as well as doing my own searches and studies of people who have done tests on it. Down where I live, it can get down to 20’s in the winter time and as high as 110 degrees in the summer. I have developed loads in the winter time with RL25 for a 300 win mag (back when I used it) that would be fine as long as you shot it in the winter but shooting it in summer was a no go because of the pressure spike from the heat. I did load work up with RL23 in my 7 MAX and 2 7 rem mags in the winter time and have shot them in summer time with no issues. People have also done temp tests that you can search on the internet with RL25 that shows that it is really temp sensitive especially 90 degrees and above. I like doing load work up in the winter time here because I get to do more shooting in the day. In the summertime, it’s really not possible for me at least because of the heat and mirage of you are shooting groups at longer ranges. [/QUOTE]
