... BTW: You reminded me of one of my favorite peeves when I see movies with Big Game Hunters: The hunter always jacks one in just before they take a shot. WT?
The same is true of Westerns where they always chamber a round in their Winchesters when intimidating someone. In more modern movies, the same display of firm intention is accomplished by racking the slide on a pump shotgun; "Take it or leave it."
I've noticed in some movies where they are going for maximum suspense you will see them chamber a round several times before one is ever fired.
