I got 3,000 fps from my older 10 twist (30" tube), when i swapped to a new 9.3 Bartlein (30" tube), 3k showed too much pressure during the load development, so i dropped to 2,950+. Shoots great at this spot, so I don't really miss the extra velocity.
I would think if you want to up your FPS... And that is important to you ... Try Reloader 33 or N570 over H1000.. The N570 is just hard to to find 99% of the time... Why do all the load work up for powder that isn't available when you need it. so I would go with the RL 33...JMO ... Dave
