Hodgdon site shows a .243 load with a 105 grain Amax at 2959 and 49,300 CUP, they show a .257 with 115 NP with the same at 3049 and 46600C CUP. For comparison they list a 30-06 150 grain load with Varget at 50,000 CUP. The 46,600 CUP/.257 load at 3049 seems low pressure as compared to the .243 and 30-06 loads. Anyone shoot Hodgdon Hybrid 100V? Does it behave fairly linearly?

Cup is a different value in different cartridges. The 243 SAAMI max CUP is 52,000. That translates to 60,000 PSI piezo max. The 30-06 SAAMI max is 50,000 CUP for the same 60,000 psi.
A 6mm Rem has the same 52000 CUP max SAAMI as your 243 but the max PSI piezo is 65,000....
All the max loads listed in your post sound resonablly accurate to me.
