Re: GURPS ULTRATECH ballistics?
Assuming a 7.5mm caseless round, that weighs 110 grains, its velocity must be 1470 feet per second in order to inflict 2d6+2 damage.
GURPS has the ammunition weighing roughly .006 lbs per shot. This measures approximately 2.72 grams Hmmm. That stinks! .06 lbs per round would be 27.2 grams - subtracting 7.13 grams for the bullet, the propellent would weigh 27-7 or 20 grams. Does 20 grams to produce 750 Joules of energy sound realistic? That works out to 37 joules per gram? Hmm. Just had a 'how much do you love your wife and daughter moment asking for ice cream. Time for me to bail out until later... One thing for sure is... 2.72 grams for a 7.5mm round seems AWFULLY low. :( |
