Here my example:
`a_ammotype 1 0 126 // 5.56mm - --------------------m16, -> meaning 126 bullets total
Now go to the M16:
`w_magazine 0 1 18 2.84 -> 18 bullets per clip
Now some math:
126 devided by 18 = 7 -> you have 7 clips when you start gaming with the M16
See? It's not that hard, it's all logical when you know where to look. Hope this answers your question.
