If we remove the chambering from the debate and talk purely about true calibre, projectile mass and design, muzzle velocity and energy, we could lose some of the emotion associated with specific chamberings.

The bullet knows none of this, and simply obeys the laws of physics, irrespective of whether the brass it leaves behind identifies as Arisaka, Swede or Creedmoor.
