We started doing this last year. Out of the 8 newbies we took to the range, three purchased their first firearm, one discovered a consuming passion for skeet and sporting clays, two received their license to carry and two joined our range.
One Saturday morning I noticed a husband and wife teaching their three kids “how to shoot daddy’s gun”. The kids were thoroughly enjoying the experience, but they only had one box of 50 rounds and mom was carefully handing out ammo 5 rounds at a time. I gave mom a 200 round box to help with “the lesson”
Now, I always carry extra ammo just in case I see a lesson in progress…
