Search on Ballistics in the forums, or on Ultratech ballistics. There will be some information there on ballistics. Also, I sent you a private message. Email me and I'll send you my derived spreadsheet (based on Doug Cole's spreadsheet) that only requires Muzzle velocity (Feet per second), bullet weight (in grains), bullet diameter (in mm) and an aspect ratio if you can find it, or estimate it at around 2:1 if you can't find it. The spreadsheet will give you bullet damage and 1/2 damage (per Doug's formulas). While the damage rating will be close to published material if you compare them against published GURPS stats, the Half Damage ratings might be a touch off, but they'll be in the ball park at least. ;)
