With 208's, it should produce top velocities. I got over 2700 fps with my rifle's 22" barrel. But RL17 matched it in that instance, and it took 8-9 grains less powder.

Seems like RL26 picks up where 17 leaves off in slightly more "overbore" or slightly higher capacity cartridges than people found 17 to be a "miracle powder" for a few years ago. My buddy and I found it to produce top velocities in his Swift and my .243, as well as with the heaviest bullets in my 30-06 and .338 WM. The .338 pushed a 300 accubond to a bit over 2500 with a 22.5" barrel. And like RL17, it seems that it has a certain applications in which it especially shines.
