I have produced an Energy Dump chart for Twilight2000 that uses the caliber's Energy Ratings (determined by bullet weight in grains multiplied by Velocity, then by velocity again, then by the constant 0.000002218) to determine the number of Damage Dice per Range Band in game. I have yet to type it up (It's my trucking co's busy season since we haul pipe). I'll try to post it for your use. All you have to do is look up a round's Energy (both the Shooters Bible and Gun Digest have printed charts in their books for my fellow "Old Schoolers"). You can find these at all of the ammo manufacturers' websites. You then compare the round in question's Energy at a given Range Band to the chart. This tells you the number of damage dice that round does in a given range band. I have ONE set of Energies for pistol and SMG rounds and a second for rifles. Be prepared to be surprised by the chart AND the Energies listed for various rounds. Preparing the chart was an "eye-opener" for me.
