Let's just say things didn't end well for the hog.
Some hunters like to use the biggest gun possible when they go hog hunting. However, other hunters like to use the exact opposite approach and hunt with really small cartridges.
Which camp are you in?
Let me set the stage for you: you're in a stand with a good rest about 50 yards away from a feeder when a couple of feral hogs in the 50-75 pound range come in and start eating. You're using a really accurate scoped rifle chambered in .22 Hornet. Using 45-grain Sierra soft-point bullets, you're familiar with the rifle and have shot it extensively.
Before you watch the video, you need to ask yourself if you'd feel comfortable attempting headshot on a hog with that set of equipment.
Watch the video to see how it all went down.
As you can see, with precise shot placement, the 22 Hornet can be pretty effective on hogs. A feral hog headshot can be pretty challenging, but this hunter had a lot of things going for him. He had a steady rest, was shooting at short range with a really accurate cartridge and rifle, and the hog had no idea he was there.
