As ethical hunters we all want to deliver a fatal blow to our prey. A well placed shot should bring most animals down within 100 yards. But if you fail to connect with the heart or lungs the tracking job can be near impossible at times. Most of us are familiar with the vital area of deer and elk but I wanted to point out the difference in deer and hog vitals.
On a whitetail the lungs are large and go back almost to the midpoint of the torso. On the other hand a feral hogs lung lay a bit more vertical and toward the front. This means that a shot that would take a deer down in 40 yards may only clip the liver of a hog.
So when you're hunting porkers keep this in mind. Just remember to aim low and forward and it should be a short and wide blood trail.
