8-10 years ago. Picture this; public range. A guy of about 30 years of age is trying out his brand-new 300 WinMag package-deal rifle with the no-name scope. Brought it to the range in the factory cardboard box.
The range has ambidextrous shooting benches where you can sit on either side. He is not sitting at the bench, he is kneeling on the ground behind the bench holding the rifle with his elbows resting on the bench. He is firing the gun with a cigarette in his mouth. His young son is sitting on the right side of the bench. The boy has his hands in his pockets, he is turned 90 degrees from the target so he is directly facing the gun, he is leaning his upper body forward resting his torso on the bench. His head is bent forward, facing downward, looking like he is bored out of his mind. His face is right next to the rifle's action and about 12 inches away. Hearing protection on but no eye protection.
I walk over, say hi, nice gun. By the way, these holes here are gas vents and their purpose is in the event of a cartridge failure they release hot, high pressure gas and bits of metal. It's not likely but it can and does happen. He should probably not be sitting so close, have him move him back behind you.
His exact reply was “Mind your own business.”
