That's unfortunate. Although it's not fun to dismiss someone from the range, violating basic firearms safety rules resulting in a negligent discharge is unacceptable and this person would be asked to sit out or leave any range I was on, competition, or otherwise. Not so sure this has to do so much with the tactical reload as much as a lack of basic gun handling skills/fundamentals, but I definitley see you your point. This is not a good situationn. I have had to ask paying customers (usually at the request of the cheif instructor) to sit out during drills and/or have taken them off for solo work over concerns of safety. Safety is the one of shooting that one must take a hard and fast stance on.
