Retumbo or US869 would be a good start.
I found with IMR4831 in both 7mm rem mag using 175 grain bullets and with my 300wsm using 180 grain bullets that I always hit pressure signs well before RL22. Have now switched to rl17 and am getting a bit more velocity out of my 300wsm. Would like to try RL26 which has good reviews to replace RL22 and is supposed to be more temperature sensitive.
