Mine was a big old fat coon.
I was in an old barn with a couple of my buddies who had long rifles with scopes and I was sporting my dad's S&W A22 with open sights. we spotted the big guy in the cupola with our flash lights and all pointed at it holding the flashlights in one hand and gun in the other.
the others didn't shoot cause they were scared they would miss and hit the tin and right then I shot, and the coon fell 30 feet down stone dead with one shot to the head. Remember it like yesterday... man was I proud lol
