Per Hayes "Elements of Ordnance" the center of mass of the gas will be considered to move at 4,500 fps.
The forward momentum should be [bullet mass] [bullet velocity] + [powder mass] [ 4500 fps ].
Per Newton's 3rd law of motion the recoil must be equal and opposite of the sum of the momentums of the projectile and the gas.
That equal and opposite stuff is not in energy [1/2][mass][velocity squared].
It is in momentum [mass] [velocity].
If the recoil compensator vents the gas sideways to the barrel, it no longer adds to the recoil.
If the recoil compensator vents that gas in a backwards direction, it subtracts from the recoil.
In 460 Rowland, getting case support is easy, dealing with the recoil is hard.
