I have noticed that sometimes when you empty your weapon of all its ammo and reload a fresh clip, it will occasionally load a random amount of ammo. I tested this without partially reloading my gun at all, so I know that the clips should all be equal. Sometimes I will get more ammo in a clip than what the gun should be able to hold. For example, I loaded a clip of 7 rounds into my K98, but two clips later, it only had 2 rounds. I have tested this with the SVT-40, G41, K98, Mosin 1930, TT33, and the C96. They all do the same thing.
