Anyone use IMR 4831 in their 6mm Ackley?

I need a free can of powder. I shoot a 6x284 56.5grs of H4831 SC is giving grate accuracy with 87gr V-max at 3500 FPS. I'm trying to reach 3,600 with out pressure signs. I've 3,550 with 56.5 grs of Re#22 but I also have a shinning ejector mark and a slightly lose primer pocket. So those are classic pressure signs. Tomorrow I'll be using Accurate Mag Pro so far 58.5grs produces great accuracy but low 3,495 FPS. Also going to try a magnum primer with IMR 7828 . Hopefully my rifle won't be bomb tomorrow.
