My son turns 9 in a few months. I never hunted much, but he loves deer hunting. He killed a doe the second time he went hunting. I need to purchase him a gun and have no idea what kind of gun to get him. Note: He's a little guy. A few buddies have suggested a 243 youth model or a 708 with low recoil bullets. While I am quite knowledgeable of MSU sports, my knowledge of hunting and guns is very elementary. Any suggestions/help would be deeply appreciated.
