I want to buy the smallest youth shotgun available for my boys to shoot. They are 7 and 5. They have pretty much mastered the BB gun, besides a little gun safety I have to beat them over the head with occasionally. They have also become fairly decent with a cricket 22, mossberg 22 and ar 22, but I want a decent shotgun for theme. Most I have seen in stores and too heavy and too long. I realize it may just simply be that they need a little more growing to shoot one effectively, but wanted to see if you have any experience in this department. My oldest is around 4'1'' I think and 65 pounds. 5 yr old is much smaller but a lot better shot!
