When I do youth and scout range sessions, I rarely, if ever. shoot. This is the kids time. If I have a kid who keeps complaining and whining that the rifle must be broken cause I cant hit the paper, I will check it with 2 rounds. 99 times out of 100, the kid is not taking instruction.
I did have one kid that I could not get her on paper. I switched instructors. He could not either. We took her to the 10 yard range and she was grouping. I checked her original rifle and couldn't hit squat. Turns out the sights were just loose enough that made it off. I made a point of telling her (and her mom) it was the rifle and not her.
I recognize the point of this thread has kind of evolved into if/when instructor should shoot but please humor me.. My first taste of shooting/instruction was at a scouting event almost 30 years ago. I had zero experience with firearms but within my allotted time and ammo i went from totally clueless to hitting on target shot after shot. I have never forget that transformational feeling. The instructors that day certainly changed my perspective because i carefully and earnestly listened to them, not because they showed me what they can do. Thank you for volunteering your time and practicing your patience with the kids- it makes a difference.
