RL-25? It may or may not. Probably a lot of other powders out there that will.
I am just frustrated, as this is the first time I have hit the jackpot so to speak in load development. 1 powder, 2 range sessions, and 55 fired rounds (I am nowhere near good enough to do the 10 round ladder test) to find my sweet spot that is staying very consistent and accurate. Last thing is need is another four, flavors of 1# powder sitting on the shelf that don't work (already have that with my Grendel load work).
Roo Roo Becky just goes on a diet for a couple months. I have 400 rounds loaded up, and 1 pound for emergency. If nothing by February, then I will try a different powder. Probably Retumbo first, then H4381 unless someone else posts a nice recipe.
