Bullet Casings

I’m requesting for models of different bullet casings because the bullet casings from CS:S are too big.

I’m requesting for the following bullet casings:

9x19mm Parabellum
45 ACP.
50 AE.
5.56x45mm NATO
7.62x39mm
.50 BMG
and also shotgun shells

The Killing Floor pack has 9mm casings, Desert Eagle casings (don’t know if it’s a .45 or .50), assault rifle casings (again, don’t know the specifics) and shotgun shells. See if these help…
