To figure this out first fire the bullet in a place with zero air on earth and see how fast it goes. The ratio between airless earth-speed and airless space-speed would be the same as the ratio between the bullet's and rifle's(As well as the casing combined with the shooter. Both of these are in a sense part of the rifle temporarily) masses. The bullet would travel slower because the rifle and shooter weigh nothing and therefore offers no solid point for the bullet to push off of.

[example]

* Bullet mass: Shooter+Rifle+casing mass = 1:100 [example]

now take this ratio and make it a fraction... (1/100).

*Subtract (1/100)th of the airless earth speed and the remainder will be your space speed.

*subtract (99/100) from the original earth speed and you would get how fast you would fly backwards when firing the weapon in space. lol no joke the bullets explosion will move YOU because YOU are weightless.

* If you stood on your space ship with magnetic boots and fired the bullet straight above your head, then the bullet would travel faster because the ship is now added to the rifles mass.

When a bullet is fired on Earth, the atmosphere will provide some air resistance & friction to the bullet, gradually slowing it down.

In space (no atmosphere, no air) one would expect the bullet to continue to travel indefinitely at the muzzle velocity (until acted upon by another force).

<<>> A bullet leaves the gun at about 800 metres per second.

The limit is the speed of light; any material object can go just below the speed of light, but never quite reach it.
