Some good powder/pressure/MV data there. Thanks for sharing.Went out today and Pressure Tested Rl26, Ramshot LRT, and N570 again as it has warmed up.

Something to note with LRT. Over a 4gr spread ES was 4.
All 3 of these powders are top performers regarding velocity. Also have RL33 but didn’t test it, I expect it will produce simular velocities.
I had planned on testing more powder and bullet combos. Might still try the 214 Hammer Hunters at some point. But it’s shooting good with my N570 load now, so Il probably just leave it alone to live out a long life of dropping animals.
Chill some over night in the freezer, inside a hydroflask, put in cooler and take to range, check velocity. I'm curious how bad the vo drops. I loaded some my 6.5max cases with lrt last night after reading this. It'll hold 74gr before compressed with a 156 berger. I only loaded to 72.5 though.Highdrum, LRT is very tempting right now but I only have one pound of it. Although I have access to more. Still might see how accuracy is, an initial node that wide is hard to ignore. It’s a ball powder so I doubt it’s stable as some of the stick powders. That’s why I like pressure testing in 100* weather.
The C is for Compressed powder charge.
I’ve had good luck and got some fast proof CF bbls. The 30SM is within 1gr h20 cap. of a 30 Nosler and I know BignGreen has a 20” 30 nos +P that’s running 215s at 2970fps. So it’s nice to see the data lining up.
