[QUOTE="budlight, post: 88395, member: 2939"] I have a 26 inch 270 win. It was many years ago that first had to pound the bolt open because of blown primers caused by heat. It was a hot couldless day at the range and like a new dummy I didn't even think about these loads sitting open in a 50 round box in the sun. I learned that keep my rounds in a cooler on hot days and I keep rounds in an inside jacket pocket or shirt pocket on cold hunting days. It keeps heat deviation to a minimum. To answer your question R-22 seems to be less heat sensitive tham my other main power for that caliber 7828. But I have not taken the time to do heat vs chrono testing I do use 60 grains of IMR4350 for my 100 grain varmint rounds [/QUOTE]
