The classic .270 130 grain factory load starts our with more speed and energy, but at 450 yards the 6.5 Creedmoor 140 grain factory A-max load has overtaken the 270 and caries more energy with a growing lead as the range increases. The 6.5 Creedmoor also allows a short action, the .270 requires a long action, and the .270 produces significantly more muzzle blast and recoil although the recoil is manageable in both.
