Pretty much any powder in the IMR4896, IMR4064, Varget, Re15 burn range works just fine. Stick powders are preferred because they light easier, so you can use a primer with smaller amounts of compound, which causes less initial pressure variation.

I'm pretty happy with Alliant PowerPro 2000-MR in my heavy 223 loads, so when I use up my last 8 lbs of IMR4064 I might transition to it if it does as well with 308.
