I just took my 7 year old daughter out to the range this morning for the first time. I recently took in a new "Crickett" 22LR in trade this month to see how she would like the shooting sports. I had looked at the Marlin mentioned above, as well as a Savage and a Stevens Favorite. The stocks were too large. The Crickett fits her perfectly.
The Crickett is a single shot bolt action. The striker must be pulled back manually after closing the action. Mine (hers!) is stainless with a black sythetic stock. It also has a key lock that prevent the bolt from closing when locked. It comes with an peep sight and is tapped for a scope mount.
I set up her target at about 7 yards at let her go. It took a while to get her comfortable on the bench and properly situated. Today we worked on sight alignment and trigger control. Different shooting positions will come later... Anyways, she had a great, safe time and is looking forward to another range session.
The rifle appears to be quite accurate and had no failures to fire with 100 rounds of Super X. Her targets were Shoot & C (?) which I thought would give her better feedback on where her shots are going. That target was difficult for her because of the black target/Black sight combination. Switching to a target with an orange bull was much easier.
She couldn't wait to show her Grandpa her targets! They are going into her box of "firsts" and awards we have collected since her birth.
For the future--she was eyeing some guys busting pigeons on the trap near us. She wants to know if she can try that some day!
