I'm looking to add a shotgun to my collection to round it out. I have been purposely getting firearms that my kids can shoot as well. With that in mind, I've been looking at some pump 20G shotguns. I was wondering everyone's opinion about 20G vs 12G for younger shooters (I learned in my last post not to refer to it as youth shooting, as I was advised to "Aim low. They're short. And lead them a bit more than you'd expect. They're quick", Thanks T.Lex) With that being said, what are your pros/cons to getting a 20G over a 12G. I'm not looking to use this for home defense, but I would like to do some trap shooting myself. Kids are 11 and 13. Also considering the cost of ammo, which is why I ruled out a 410.
