For firearms I couldn't find a value I would use some charts found on the internet for general lengths to MV for different types of ammunition.

What I've done thus far is take the MV from the cartridge manufacturer and compare their test barrel length to the weapon's barrel. I then adjust the MV for the weapon by +/- 25fps per inch difference. this is a rule of thumb I was taught years ago but I have seen a figure as high as 50fps/inch in some forums.
