A round designated as .45 Colt, developed and released for public sales in 1873 that weighed 255 grains, and had a muzzle velocity of 855 feet per second, its average damage worked out to be 8.5 points, or 2d6+1 damage.

In order to reduce the average damage to 8.5/2 or 4.25...

The velocity must now become: 440 feet per second. Not half the velocity to be sure, but that's what I had to change the velocity value to get a damage of 4.25.

I'm guessing however that this is not necessarily what you meant. Am I right?
As a normal thing Gurps firearms damage _is_ linear with velocity. The not-quite matches in your examples are possibly rounding issues.
