One thing when kids are on range - the focus is the child shooting. Don’t plan on shooting. The ranges want to see an adult watching and helping kids at all times.
RFGC has a FREE kids shoot once a month.
http://www.RFGC.org What kind of shooting? Rifle is most common. Handguns will Depend on child/gun. Shotgun is all about size of child.
Also to note for taking kids to RFGC with a .22. You can shoot on the pistol range (15-50 yards) and the best part. So long as the kid can keep all their shots on the backstop. They can shoot FAST!
Take some clay pigeons as reactive targets!!
Also to note I started taking my son at age 4 and he is 9 now. He can make that 10/22 fire like he had a bumpfire stock on it. So be warned. It becomes costly after a while.
