As has been explained above, it's a compromise on barrel life.
Push more burning powder/gas through a smaller bore, it erodes faster.

The .260/6.5 Creedmore are great "compromise" chamberings, as is the 7-08; I use both (as well as the .308).

While it's easy to say "barrels are like tires, just replace them", the mechanism to have this done, and in a timely fashion if need be, should be considered.

Gunsmith waiting times can be months, to many months...

This is why a lot of us like the Savage platform (and the same can be done with the 700 platform) because of the DIY barrel change ability.
