Shot placement is everything when it comes to hunting. This Texas hunter proved that by instantly killing an invasive wild boar with a single shot from his .22 rifle.
In most cases we would recommend against using a .22 LR for hunting medium game, but since wild boar are a destructive invasive species anything that will kill them is good enough. If you stick around to the end of the video there is also a cooking segment where this hunter prepares his harvest.
