I've had great results with 4831SC and it HAS produced 3,000+ fps for me and I'm only at 800ft ASL. Here is my load info:
Surgeon 591 7wsm
24" Bartlein 1:9
168VLD
62.9gr of H4831SC
Avg: 3,032 @ 85*
SD: 5fps/ 7fps
ES: 14fps
3.212" measured off the Ogive
I've shot this load for a while now and it's been verified on steel out to 1,200yds and fur out to 780yds.
I switched from RL22 to 4831SC due to temp issues with the RL22 in the summer time.
