I looked at my 77 data that involved only two bullets and two powders. With CFE 223 I shot 2865 at 29.0 in 70 degree weather. The same load from Nosler, shooting 39.5 and 28.5 would be about 2908. Mine wasn't showing any pressure. I was more interested in the light bullets for PD's. Component/atmoshperic variation may be at play.
Ritch shot some 55's using 31.3 CFE Rem 7 1/2's and this was what the case heads looked like:
Not good with the swipes evident at their mid level loadings. Remember that while the head is 223 it still gets the bolt thrust of the 6.8/HAGAR sized case, Unlike a 223 at XXX pressure you will see more brass hammering thanks to that little bit of physics on the Nosler.
I have not 55's in mine but I have shot 50's using 33 of CFE getting 3553. The 55's from Nosler at 33 show 3518. CFE was not my powder choice on the 50's and I ended up using 31.5 of RL15 at 3734. Nosler with a 55 shooting of 31.5 RL15 shows 3437. The 50's are like an atom bomb when they hit a PD.
The 22X6.8 is set up to hit the lands early and can be reached at standard magazine length less than 2.260. Ritch has pressure tested all my loads and on the 50's I could have, and do, gone higher with a nice cushion. No brass deformation on them and the pockets are nce and tight after half a dozen firings.

Thanks for the info. I have been curious of how they stack up side by side.
