I'm picking the Lapua brass maybe has a fair bit less capacity? Have you measured case capacity by chance?

Good example of why to not get your load data from forums or skip doing the workup.

I haven't measured the case capacity but I might when I get the time. I have a couple 2x fired lapua and 7x fired hornady to compare.

I'm running a suppressor which could be causing the earlier pressure? or I have a tighter chamber/barrel? I could shoot 57gr but don't want to trash the brass early as it is bloody expensive and hard to get.
Its a lightweight 18" barreled hunting rifle so don't really need the fraction more velocity of the hotter load. Even 2800 fps is more than i really need.
