Thanks for the update. I talked to Petersen about pressure signs with their brass and you likely won’t see them until you are way over. Just an FYI.
Looks like your getting promising results. I’m playing with the 265 CELs right now using RL26. With I could find some of the N570

Ya, that is kind of what I figured, so I'm gonna keep my load aroumd 88 grains or so. In a action designed for the larger cartridges however, you could get some crazy performance. In my buddies stiller TAC 338 with a 28" barrel using peterson brass and retumbo, when trying to find max pressure I got the 300 Bergers over 2900 and still wasn't having any pressure signs!! I backed it down to 2750 and it's happy there.
