I am making an FPS and I wanted to make an ammo counter. 30 rounds in gun/90 rounds extra. If it requires python, so be it.
(P.S. I just got upgraded to Blender 2.47)
Made an example with only logic bricks.
shoots 5 bullets per rounds (you can change the numbers)
Hopes it helps, ask again if not 
and have a good day!
