My cousin did something similar. He thought it was dead but as it turned out his head shot was more of a riccochet.When I was a sprout my dad would give me 4 shorts to squirrel hunt by myself. I wasn’t old enough to figure out ways to get extra ammo, didn’t buck the old mans rules. Didn’t waste my ammo. Shot big fox squirrel and it wasn’t dead. Trying to get away I put my foot on it. Wearing the old PF Flyer tennis shoes. That squirrel wrapped his paws around shoe like he was eating a sandwich. He poured the teeth to me. Lucky my toes were hanging out under my heels at the time. He bit through the toe piece.
