Well yes and no
the common bullet weights for 6.5 available, that work with standard 6.5 twists, are better then the comon bullet weights for .308 that work with common 308 twists.
Those 6.5 boolits will outperform those 308's.
Obviously if you get custom 30 call barrels with higher twists then commercially available rifles, you can go up in bullet weight and length and obviously all bets are off.
I know a guy who has a 32 inch 308 , and he can pretty much equal 338 lapua ballistics.
But it sure as hell isn't a commercially available gun, and he sure as hell can't shoot commercial ammo for those results.
6.5 offers better bullets with better wind resistance out of standard 6.5 barrels then you can achieve with 30 cal barrels and bullet weights.
