Interesting replies, again thanks for the added information.
The 180gr bullet was chosen to give an apples to apples comparison.
Yes the data can be skewed toward the bigger rounds by using heavier bullets, or show less of a difference than is realistic by using lighter pills. And yes, manufacturers load data is not the end all be all of information to consider but when starting a decision like this it is at least that- a place to start, and errors in the data are likely to be consistently low or high across the board, not leaning in the direction of one round over another.
As stated, any choice will by necessity be a compromise.
While the 30-06 is slower than the rest the extended barrel life is appealing, as is the lower recoil and powder charge. Maybe an AI version just for grins.
The 300 WSM
doesn't handle the heavier bullets quite as well as the 300 WM but uses less powder and has better barrel life.
The 7mms have been mentioned, maybe a 280AI?
Again, compromises. Yes barrels don't last forever but I'd like to at least get a couple of years out of it.
