In Hornady's 6th Edition I found the following comparison between IMR 4831 and H 4831 regular in the 300 RUM. Using a 110 grain bullet they report
3800 fps with 93 gr. of IMR and 101.4 gr. of Hodgdon. The heaviest bullet they show IMR data for is in the 150-155 grain range.

Just looking at Hornady's data I would have to give Reloader 22 a try for the mid weight projectiles.
