[QUOTE="RevJim, post: 1939378, member: 86754"] I've used alot of IMR 4350, I grew up in East, Texas, and overall, I never saw any change in my zero from hot to cold. However, when I moved to Utah I went to the Extreme Powders years ago. However, I still use many older/newer powders too and IF ( a big if) my rifle changes zero from any temp swing, I drop that powder. I'm way too OCD about Reliability, ha. I've found that the temp issues have alot to do with the cartridge/powder/bullet combo. For example, you can read of R17 being sensitive, but in my 300WSM/168 TTSX it shoots as well at 90 deg as it does at 40 deg. Only way to know for sure, is test it yourself. I load all year long, because I love it, so I keep notes. ( I have to add, since I've never been overrun by any game animal, could it be that maybe they know my guns always go "bang"?, hmmm? :) [/QUOTE]
