There's faster powders for sure but in this rifle I tried H335, IMR4198 & W748, none were more accurate and 3100+ is still fast enough for my use.

I'd kind of forgotten about this powder till a few months back when I realized I had a few pounds. Don't mean to get too far off the subject but the way things are getting it's good to have a lot of something like this or RL15 that'll work in a wide range of cartridges.
