I don't see this discussed much. Thought it would make for a good discussion. Basically I am mainly interested as it pertains to handguns. Anybody done this enough to comment on it?
I got curious after that story of the cops in the bar who filled a pickup truck full of lead and missed the driver so I ran some numbers.
For a 45acp the lead looks something like this:
0.5" per mph @21'
1.0" per mph @50'
1.5" per mph @75'
Typical person runs at about 10mph so a broadside shot directly at a running person 50' (16 yards) away is going to be a clean miss. On a car moving 3 times that speed you're looking at almost 3 feet. On a car going twice that speed you're probably looking at an aimpoint up around the front bumper!
Doesn't this assume you are sweeping the gun along with the target? In other words if you pick out a single aim point in front of a moving target you'd probably have to double these estimates to get a hit due to the time delay involved in your own reactions?
