Personally I'd want at least a 22" with a 243 or 6mm CM to take advantage of the cartridges potential.
I read some reports that the 6mmCM has slightly better throat life than the 243, but I feel like that is so subjective to how you load/shoot your rifle..
I have a 243 Win R700 with over 2k rounds down the barrel that still shoots sub moa and produces great velocity.. I've never shot it in rapid succession, and keep my load at or below book max.
Alot of the barrel life numbers come from competition shooters who really push the limits with thier handloads and can fire alot of rounds in a relatively short period of time.
