Audio problem: When Tango and Cash first meet the Assistant Warden, somebody dubs over his voice and the words don't match his movement - and it is very obvious that it is not his voice. (00:45:00)
Audio problem: When Tango takes his first shot at the tanker at the beginning, the guy in the passenger seat says, "Shit!" However, the way his lips move, that can't possibly be what he's saying.
Answer: He was doing a combat reload, where you eject all the rounds, spent or not and fill the revolver with new ones. It guarantees six shots, rather than relying on "indexing" where you count every round fired.

That doesn't make any sense since he hadn't fired a single round and the gun was fully loaded.
It's hard to tell, but it does look like there were at least some empty shells that land on the ground. A revolver isn't going to eject spent shells, so there's no way to say it was fully loaded.
