changing the ammo in a mag

[CooK]

is there a possible way to chage the ammo amount in a magazine, say for instance you get a m16, w/ 2 clip.
i want 1 regualr (30 rounds) and anouther with 10 rounds.

this possible, and if so how?

I believe this would take a custom mag ( = an addon )  :-\

Unless ya got some AI moron to fire at some dummy object to partly
empty a mag... but it would prolly be most inaccurate... so... ADDONS!
