Re: GURPS ULTRATECH ballistics?
Quote:
Volume of tip = 2/3 * pi * r^3 Volume of cylinder = pi * r^2 * (length - r), or pi * r^3 * (aspect ratio*2 - 1) where bore is bullet bore in milliimeters and aspect ratio is bullet length / bullet bore. Accumulating variables, we get pi * r^3 * (AR*2 - 1/3), or pi*B^3*(AR/4 - 1/24). |
