RL-26 has proven nothing short of amazing in my 240 Wby. It's worth 100 fps over MRP(previous go to) when launching 95 Gr NBT's. Substantially tightened the groups up as well. I've pretty much experienced similar results shooting all bullet weights from 75-100. I'm about to begin using RL-26 in my 6.5 Creed. Expecting the same results there as well.
