There is simply no "momentum vs. energy" question to complicate.
There is no measurement for what effect a bullet will have on any given target. Some bullets are better than others. Some go faster, some go slower, some are lighter while others are heavier. We can go on and on about which one is better till we turn blue in the face, but there is simply no way to seperate energy from momentum........veloctiy squared and multiplied by weight and devided by twice the ecceleration of gravity is the method currently excepted by the industry to calculate energy, momentum, force, push, umph, whoop-ass,,,, whatever you want to call it.
Back at the turn of the century ammuntion manufacturers would just hang a cadaver by the neck, shoot it and measure the swing imparted by the bullet transfering said energy, momentum, force, push, umph, whoop-ass to said target. While this might not be considered reasonable by todays moral standards, it was no doubt a more scientifically accurate means of measuring energy, yet didn't seem to offer an industry standard to apply to such a wide variety of designs.
Bottom line,, there is a difference between measurment and calculation
of forces contained within a moving object, but there is no difference in the forces applied that depend on the name you give them.
Furthermore , this MASS LOSS reference is governed by bullet design, not bullet weight and speed.
