Whether you choose to risk your inches to wind deflection or bullet drop, you can't dispute the wonderful performance and versatility of both these cartridges. In energy, velocity and drop, the 270 Winchester wins. In wind deflection, recoil, cycling speed, and potentially compact rifle size (short action,) the Creedmoor comes out on top.If you own an accurate, beloved 270 Winchester, you don't need to replace it with a 6.5 Creedmoor.
