I've had people tell me, and now I see it - when I drop a weapon, then pick it up I'm given the amount that is in my clip plus the amount in my reserve.

So if I have 30/119 when I pick it up my reserve will have 149, any suggestions on how to stop this?

I commented out this line in the shared in the weapon base
self.Owner:GiveAmmo(mag, self.Primary.Ammo) alas, no results.
