I like 3031. I use it in 7mm-08, .243AI and recently in 6mm Rem. It's relatively fast and reduces muzzle blast/pressure in my 15" Encore. According to QuickLoad, it should produce near max velocity of any powder in 6mm Rem and .243AI with light (55gr) bullets. I haven't finished my testing though. It was at one time THE go-to powder for .243, but I think 4064 has surpassed it.

Incidentally, in terms of searching for accuracy loads, a full grain jump is too much with charges in the 40gr area. You want to use no more than 1% increments, which would be 0.4gr.
