I'm a 748 guy for .30/30 and haven't worked with cfe but anything that gets 170s over 2K is good stuff. Reminds me of the time I had to switch to AA#2 for steel plate loads because....out of 231 and Hp38 they worked just fine and I "found" a new powder for .45.
Isn't IMR 3031 the gold standard for 30-30?
I use it for 308 and it's equal to if not better than any varget or 4064 loads ive developed.
