I know a guy who did a "30.06 against a Dodge Dakota" kinda thing. He was out hunting deer and saw a buck off the side of the road. He got so excited he jumped out of his truck, laid his rifle down across the side of the bed and took a shot at the "deer". Trouble was he was shooting across the bed of his truck with a scoped rifle. The bullet impacted the inside wall of the top of the truck bed about 3/8 from the top of the bed and BLEW a nice ragged hole out the other side of his bed.
The icing on the cake was the "deer" was a prop setup by the local game and fish guys who jumped out and gave him a citation.
he was not a happy camper.
