I also have never been one to buy into the "temp. sensitive" thing much, if at all. I just know that he came to not like the R- 22 so I started loading the short cut for him instead.
My solution has always been to sight in my hunting rifles under the temps in which they will be used. Problem solved. I have been preaching that for YEARS now. I still burn plenty of R-15 and R-7 in cold temps. It has never been a problem.
It is my opinion, that if anything, IMR 4831 is more temp sensitive than R-22. But 4831 sc is better. According to ES figures on my chrony any way. Again, sight rifle in under hunting temps, and it is a non issue.
I do try to use a temp stable powder for dedicated target rigs that may be used in a variety of temps, but that is another story....
