I use 23.5 grains of H-110, Hornady 240 gr. XTP, and CCI350 primer. The other night I shot a 10 shot group through the Chrony and the average shot string equaled 1,401 FPS using this combination.
I was using a scoped Ruger Super Redhawk with a 7 1/2 inch barrel. I can shoot 1/2 inch to 1 inch groups off the bench at 50 yards and 2 inch groups at 100 yards.
