I tried 26 with some other 150-grain bullets this morning. 61 grains with Partitions is a little warm, judging from the muzzle velocity of close to 3100 fps, so I'm going to back it down to 60, but it was about right with 150-grain Long Range AccuBond.
That's pretty righteously impressive.
I've used MRP/RL-22 forever in my 270's with 150 Partitions forever, & those go 2900-2950'ish from 22" barrels so that's a genuine improvement.
