The velocity of the 270 is more on par with the 6.5 PRC than a Creed at the muzzle using factory ammo. But as it was shown it don’t take long for the 147 to catch up due to it’s slickness. I really like the 147 and it’s done well for me. Haven’t killed with the 145 yet but showed a lot of promise out of a CA Ridgeline.
