RL26 has been really good for me in the 270 WSM, 7 WSM, 338 Win with 225 PTs, 35 Newton with 250 PTs, 243 Win with the 90 AB, 25-06 with the 100 ET and the 7mm MSM and 150 ET.
Great speeds across the board. What I've noticed though is that like a few other slow burning powders it doesn't strut its stuff till I hit the upper loads. It was really apparent with the 338 and 35 Newton but man, once it gets there it has been really decent.
