I ran a ladder on the 143ELDX with superformance in My Bergara 6.5CM HMR. Starline brass and federal 210 small rifle primers. I went from 44gn to 47gn. 45 seemed to be the sweetspot after that I was getting significant primer cratering and the groups started to open up. But to be fair this was in the Bregara and not the Sauer, however the Sauer seems to have quite tight chamber and a shorter throat so I doubt I could comfortably push them harder than I already have.
