The scene in Ronin when Deniro shoulder fires a rocket at a car. That was dope.
The scene is peacemaker where Clooney used the mercede's wheels to blow up the car and then bust some caps in the guy in the other car stone cold style.
That scene in Last Man Standing where Bruce Willis busts caps in the guy with both his 45's and knocks him off the porch and into the middle of the road.
The scene in Full Metal Jacket where Mathew Modine busts a cap in the vietnamese sniper girl. "Fuckin hardcore man".
But, of course, the grand daddy of them all, that SICK ASS scene in The Professional where Leon practically takes down a whole swat team by himself.
