I use IMR-4895 Surplus Military Powder with a 150 grain Remington PSPCL bullet in a Browning BAR Lightweight 30-06 with a 20 inch barrel. Five shots across the chronograph averaged 2848 FPS and the extreme spread was only 33 FPS. At 100 yards the 5 shots measured 1.187" center to center of the two farthest holes.
I think you will be pleased with 4895 powder, I know I am, I use it in 223, 30-30, 30-30 Ackley Improved, 308, 30-06 and 45-70.
