Dram Equivalent, as used today, is not a measure of energy. It is simply an indication of velocity.

Example:
A 12 Gauge 3 DE load with 1 ounce of shot gives a MV of 1,235 FPS and a total ME of 1,481 Ft .Lb.
A 12 Gauge, 3 DE load with 1 1/8 ounces of shot gives a MV of 1,200 FPS and a total ME of 1,576 Ft. Lb.
A 12 Gauge 3 DE load with 1 1/2 ounces of shot has a MV of 1,095 FPS and a total ME of 1,746 Ft. Lb., or roughly the same ME as a 3 1/2 DE load with 1 ounce of shot.

I still think in terms of Dram Equivalent loads. I don’t care what labels the manufacturers put on their boxes, but if they do away with DE labeling I’d be willing to bet that their published velocity figures will still (usually) fall along the DE values. They do today.
