Don't short change that IMR 3031 In my 25lb 308 benchgun 37.5gr with a 168gr SMK's shoots in the low 1's and had done a pile of winning. Some of that old powder still works better than the new stuff. That being said the new stuff work awful good too.
I use it in my 30-30 and 45-70 loads too.
Not shabby at all
