I once loaned a .20 cal pellet rifle to a guy. He hid it from his very precocious 2 year old daughter, under the bed. He couldn’t find her, and went into the bedroom to look. A pellet slammed into the baseboard, not far from his foot, and he heard laughter under the bed. Why it was loaded and cocked, I couldn’t say....
Hard to believe a two year old girl could load and cock that rifle...
