Hunting/pest control last year. Shot a coyote on a buddies farm and thought he was only wounded i thought i had missplaced the shot as he was running at the time and i thought i saw him keep running. I ran full tilt the 200 meters to where he was when i shot him to start tracking and put him out of his misery. Turns out i had not misplaced the shot and he dropped less than 5 feet from where i shot him, hit him right in the boiler destroyed both lungs instantly.
But man i hadnt run that hard in probably 20 years, and carrying a rifle and 40lbs pack to boot.
