Both our boys started on Chipmunks, which are like a Cricket. Single shot bolt guns. They learned to shoot with them from field positions, and I always made them work the bolt like it was a repeater as they were learning. Great, accurate little rifles that are scaled to fit kids, so it makes for easy learning. When they both got to be around 8 or so, they each got an FR8 in .308, and they never skipped a beat. Between range trips, they sat in front of the TV with strippers of dummy rounds, dry firing and reloading using the strippers until they could do it in their sleep. Learning the basics young pays off big time.
