Well... actually for me, the felt recoil is exactly the same between my 6.5PRC and my 6mm Creedmoor...
But my 6.5PRC weighs 10lbs all set up with suppressor, scope, etc... and my 6mmCM only weighs 7lbs...
Recoil is merely a factor of the weight of the rifle system. More weight decreases Recoil, less weight increases Recoil... so, my longer range capable calibers get bigger scopes, heaftier suppressors, longer/thicker barrels, etc that all add a bit of "useful" weight... and that makes all my rifle systems equally shootable.
