[QUOTE="sodakota, post: 2232538, member: 81002"] If you live in an area and hunt in an area where temperature extremes during hunting season you'd be a fool you ignore temperature sensitivity, in my opinion. The temperature in South Dakota could be in the upper 80's or 40 some below and I hunted at both extremes. It's not just about accuracy! It is also about sky rocketing pressures in high temperatures. Some powders are quite temperature sensitive, in particular, the early WW ball powders. I have had issues with 785, 760 and with 748. Hodgdon has some identical ball powders as the WW ball powders. Years ago I had a WW785 load in my 300 Win Mag that was quite accurate during testing and when I took it out the temperature was close to 100. The case froze in the chamber, I had to take it back to the shop to get the bolt open and the case out. That could have been a ruined hunt. In a poorer action it could have meant a lost eye - I use shooting glasses ever since that incident. WW760 and WW748 are as bad, in my opinion. But IMR4350 is not too bad as far as temperature sensitivity, at least I've not noticed it. I have IMR4350, H4350, AA4350 and IMR4451 on hand. Of those, if I were starting out with one powder, I'd probably go with IMR4451, or perhaps H4350. Having said that I've used IMR4350 since the early 60's without a problem. I still use it. I have not played with AA4350 to have an opinion.. [/QUOTE]
