RL 17 is awesome with the 7-08.
I didn't use it with 140 but instead the 150 eldx and was 2895 FPS with 24" bbl . That's was one of my best shooting guns I've ever had. It would group 3" or less at 600 yards
A couple of weeks ago I found a good load at half MOA with 45.5gr of RL17 and the 150gr ELD-X, now I need to verify it and see what speed I'm getting.
RL17 is a pretty well rounded powder, works great with bullets from 120gr to 168gr in this cartridge.
