[QUOTE="Turpentine21, post: 2681628, member: 124909"] I have to be very careful of temp sensitivity in general. I do work up my loads in cooler weather but with the knowledge of the fact that a lot of my work with those loads will be in June or July. Years ago I worked up a great 308 load with ball powder at 50 degrees. I wasn’t as aware of the effects as much then. I had read about them but just wasn’t as concerned. I decided to test it on one of those 95 degree days. That pretty much drove the point home. I didn’t have a catastrophe, but there were definitly signs of excess pressure. Bolt lift was the first clue. Brass inspection proved it. I use Varget, H4895, imr4064 and AR comp in my 308 loads now and they hold up well to excess temps. I’ve tried some ball powder in 6.5 Grendle but Ar comp and 8208 are a bit more predictable. 8208 can get away from you quick if you run it close to the edge. I have IMR 4350 and H4831sc in 6.5-06 and 270. I try to use the H if I’m worried about hot weather. Even then it’s a good idea to not run right on the line. [/QUOTE]
