I have two that I am going to be doing load development for. I have a pretty good selection of 140 grain projectiles to play around with and most of the go to powders. I've had good success with H4831 and 140's. I would like to try some heavier rounds, but only have 160 partitions to play around with. So my question is, have any of you tried R26 in the .280AI with lighter rounds? If so, what were your starting points for ladders? I've been reading about people loving R26 but load data is scarce to non existent for most bullets. And if anybody has any 160 Accubonds or something similar you're willing to part with, I would buy them.
