I've seen quite a few debates on here and other sites concerning shooting at running deer. This subject comes up mainly due to the shotgun season with pushes and drives happening and a lot of deer running. I was thinking about this yesterday a bit and decided to take a closer look at the actual distance that a deer should be led if a running shot is to be taken. This may not be the case with everyone, but I would say the vast majority of people out hunting whether they be newbie's or veterans have no realistic perception of how far a deer will move between shot and impact. So.......let's break it down a bit.
Let's say we are using a 12ga that is sending slugs downfield at 1700fps. This is not the fastest nor is it the slowest, just a good round number to use as an example. Now let's say you are shooting at a running deer (top speed of a whitetail is 30mph, so lets say it is pretty much balls out at 25 mph) at a mere 50 yards.
At this distance, it will take (50 yards / (1700 ft/sec * 0.33 yards/ft)) = 0.089 seconds for your slug to reach the target. In that 0.089 seconds, that deer will have moved (25 MI/Hr * 0.000277 Hr/sec * 5280 ft/MI * 0.089 sec) = 3.25 feet!
Now take that distance out to 100 yards and all of a sudden we're talking a 6-1/2' movement.
I for one am not a big advocate of shooting at running deer, if it's possible to get them to stop or at least slow down, that should without a doubt be done. I would be willing to bet that most running shots are taken free handed, it is hard enough to take a good free-handed shot on a standing deer at 50 or 100 yards, now add swinging with the target and compensating for the correct lead distance in a very short couple of seconds from the point when the deer is spotted to when the shot is taken and you have added another HUGE dynamic to the shot process and difficulty. A dynamic I feel confident in saying MOST people are not capable of compensating for correctly (including myself). I'm not trying to tell everyone don't take running shots, just thought this little bit of info may come as a surprise to some of how much you actually have to lead a running whitetail. If you KNOW you can ethically take that shot and you KNOW there is nobody standing behind your target, then go for it.
Good luck and happy hunting!
