Got an extra 75fps or so out of my 25-06 with RL-17. That being said, RL-22 gave me almost 150fps. This was using 100gr NBT's. I still prefer H4831sc though. It's more consistent as far as velocities and group sizes.
With RL17 and 22, one day it may print a .50 in group, next day it opens to 1.25 in. I don't have this problem with H4831. It always group's .75 or better, unless I screw something up.
