Rl-26 is the bee's knees from what I have read. I think I will start there with 140's.
Do you have any info on RL26 in 6.5x47L with 140’s?
No. I don't.
But i have 3 pounds of 26 now and a 6.5 Creedmoor that's hungry.
Made up a few loads tonight with 140gr eld-match, and 143gr eld-x Hornady. It's going to be tough to get max powder charge (quick loads) in the case if I can make it that far. In the Lapua case, I'm just not sure you can drop tube enough RL26 in that case to make a gain. Creedmoor, maybe.
There is the RL16 though that's made for the case size. Temp stable, and of course, hard to find. I'll post up what I find.
