It's not just marketing. The SAAMI chamber and twist rate makes it possible for factory rifles to shoot factory low drag ammo and perform.
No 50 flavors of match chamber like the 308, and honestly no real need to play the "what freebore do I need for my custom reamer?".
It was a good plan executed at the right time. I dropped 260 for the 6.5cm purely for the ammo/barrel availability. Couldn't get 260 match ammo for even close to the same price, and it didn't shoot as good. Sometimes it's nice to not reload.
Ultimately it was one piece in the changes that made LR/PRS style shooting extremely popular and has contributed to the growth we've seen in the last 10-15 years in this game. Made match ammo, decent performance cartridge, in factory accurate guns available to more people for less money. For better or worse lol...
