Not me, but my buddy.
A group of us took a self defense handgun class at an outdoor range. Next door were some LEOs practicing with their nice full autos. When our instructor gave us the cease fire, everyone decided to take a 5 minute break. It was hot, and everyone brought water, hats, shorts, etc. My buddy, who was 3-4 feet away from me felt a bump on the side of his hat...I saw it, and I was like, "Hey you O.K.?" He was surprised, "What the heck was that?" while checking his head for any injuries.
A richochet from the LEOs came over. SCARY. It was inches from his face. After that, I always wear hats at the outdoor range.
