IMR 3130 powder ???

[Slamfire]

 I have been using 3130 in my rifle loads and have had pretty good luck with it. NOW the question,,,,, is 3130 temperature sensitive ?

I ask because i read a review that said he (the person) could not get 3130 to accurately shoot in any of his rifles and it was too temperature sensitive. He said 4198, and a few other powders all shot in the same rifles were "more accurate" than 3130, what say ya'll.

My only experience with IMR3031 vs IM4198 is with lighter loads in .45-70. IMR3031 is slower-burning than IM4198, and may leave more residue in the form of unburned powder. I don't think 3031 is all that temperature sensitive. For example, I have used it in loads of 48 gr. in .30-06 with 150 gr. bullets, with no problems. Functioned in an M-1 Tanker Garand (18" bbl.) just fine down to around 30 degrees. (Didn't use it at sub-zero, however.)
