have a look at this guys. I seem to remember that this is not a new idea and it was called something else before.
it is quite interesting in that it seems to count sectional density of the bullet.
Ie two bullets of the same wieght and the same impact velocity ie 7mm and .308 at 2900 fps 150 gr the 7mm has a higher rating.
