VS Shotguns

This is of minor importance, but why is it the VS shotguns now have a "shell rolling across the floor" sound after firing? I'm mean honestly... let's be a bit less generic and more creative here.

Because VS shotguns now eject double A batteries that roll across the floor ?

Is it all of them, or just the pump-action one? That one does have individual ammo.

That put a smile on my face.

I love the idea that the amount of power in a double A could kill a man in a single shot.

So how fast do the pump actions kill someone?

The original shotguns kill so fast,makes me think these pump actions are a 1 hit kill or what?

1 hit a point blank, fires about half as fast as the nova, 5 rounds

Oooo goodie,LA's are going to have a field day with this..
