Brad,
Looks like you're already doing fine with 4350, but be sure to give the 4831 a try too. I've had good results with both 129gr Hornadys and 130gr Accubonds when loaded to just over 2850 with H4831. I think the SC version would likely be better still. Less crunch when seating the bullets....

My rifle however definitely prefers 4831. Only proves that the rifle knows better than us what it likes!
Well, once again proved this to be true!
My rifle's 1-9" twist seems to prefer 120-ish bullets. H4350 gives good speed and average accuracy (3/4" - 1.25"). Decided to experiment with H4831sc and the 120 bullets. Everything shrunk immediately.
Shot these two in a row:
Going to try H4831sc with 130 and 140 grainers as well.
