Dirty Harry

I know what you're thinking... Did he fire six shots or only five?
Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question:
Do I feel lucky? Well, do ya punk?
Hey, I gots to know...

He only fired 4.

I count 5 clear on-camera shots, and there is possibly one muffled, off-camera shot. The obvious shots in the full version are:
0:21 - One shot at robber who fires shotgun at Harry.
0:23 - One shot at robber diving hear first into car.
0:30 - Two shots into car windshield.
0:42 - One shot at robber escaping car on its side.
There are possible shots at 0:26 and 0:40, hard to tell. The one at 0:40 is more likely, as the car and water may have muffled the sound.

@@hrajotte Harry cheated. Even if he had only fired 5 shots he drops the hammer at some point and when he turns back around he cocks the hammer again which rotates the cylinder. If he fired 5 shots the cylinder is now on round 1 (used), if he fired 6 shots the cylinder is now on round 2 (used) so no matter what he's pulling the trigger on a used round.
