4831sc or maybe RL26. H1000 is the standard but a bit less velocity.

I get great sd and es loading eldx 212 with 4831sc loaded to hit 3000 fps. Not going to say the load because it is warm. Start at book and work up to find a node.

Most modern powders are gtg. What temps are you fluctuating in?

H1000 is what I settled on and stuck with, pushing 200 grain accubond bullets pretty easy to 2860fps with very good accuracy.

20ish in winter and 90s in summer is probally the yearly spread, we shoot a monthly match year long

Anything in the 4831 burn rate is a bit too fast for 200's. You need to be looking in the H1000, Retumbo. Reloader 26, Ramshot Magnum burn rate.
