Ok, I am going to buy my son a rifle that will be his once he is old enough to start hunting(Another few years). He is 5 years old and already shoots his pellet gun and .22. I need some suggestions on what caliber to get him. I have read the ballistics on the .243, 7mm-08, and .308 until I can't see anymore. I don't want a .223 bc I already have one. If you ave nay thoughts please share them with me. I like Winchester, Ruger, and Remington the best but I am open to any manufacturers, Thanks.
Side note: Does or has anyone ever owned the Mossberg Super bantam with the butt pads that can be extended as a kid grows?
