When the mosin is empty and you shoot the "click" is audible from around 550m away, me and a friend tested it. This might be the same with other guns.

Just shoot an empty mosin
I need to ask: are you sure this is ingame? Or is it something you're hearing over skype or teamspeak?
I can hear my friends on skype being attacked by aggro zombies, hear their gunshots and also their clicking from empty weapons.
