H-4831 never gave me the Velocity I wanted same with H-1000. R-22 or IMR-4831 gives me 3500+ fps with 95 grain Ballistic tips and a 3 shot group in the .2's at 100 yards.I would start with 50 grains with either one and work your way up. I would use the 95 Ballistic Tip I have shot Deer out to 480 yards with them and they work great. Another Powder you can try is Varget I would start at 45 grains and work your way up. My setup is a Rem 700 Long Action with a 28 inch Hart Barrel with a 1x9 twist. Let me know if you have anymore questions I have tried lots of Bullet and Powder combo's in the 6mm-284.
