I didn't think so. I've been going to gun ranges since I was 12 and never heard of it happening.
I was at Blue Mountain Sportsman Center in Peekskill NY the other weekend and I brought my young cousin to try and show him what gun safety and responsibility is all about. He's into 'hip-hop' culture and unfortunately that left him with some very negative ideas about how to handle firearms. I wanted to try and impress just how serious guns are and also how much fun shooting can be.
I have to say that I have the upmost respect for Range Officers generally speaking but the one they had on staff was incredibly rude. I had my cousin firing one shot at a time, I was loading the rounds for him and this guy was just looking for something to jump on him for. He had the barrel resting on a sandbag and the officer YELLED at him stating 'TAKE THE BARREL OFF THE SANDBAG! Its going to overheat and the bag will explode sending sand everywhere!'
At the rate of one shot every minute or so, I am doubtful the rifle would have generated enough heat to even burn his hand, let alone make a sandbag 'explode'. We complied, as anyone should when at a range, but it pretty much ruined what I was trying to impress on my cousin. If its your first time out at a range and someone yells at you over something so ridiculous, its tough to want to stick with it.
Anyway, I'm very disappointed. I've been to Blue Mountain several times and had no problem before this point. As a Range Officer, that guy should be helping and encouraging, not yelling at him over trivial crap.
