Like I have been saying it is Energy that has a tighter measurement of the 308 class cartridge.
If the ordinances are sorted for acceptable sectional density....
There is less difference between the rounds in energy than velocity.
KE is how a non explosive projectiles harvests game.
Without the proper KE the ordinance won't open and do its deal.
Unless it is an arrow.
But then kinetic energy is measured in marketing archery equipment also.
So go figure.
