I have a 13 year old son and I am considering buying him a shotgun to use for clays and dove/small game hunting. He is a wrestler and a small one at that. Currently he is 86 lbs so I am leaning towards a 20 ga. I have a Mossberg 500 set up with a red dot for his turkey gun and would like to get a semi for him. I don't want to break the bank on this gun and am thinking no more than $400 at most on it. I would love to have an 11-87 but they are typically a little more than that. I have seen some nice franchi 48ALs for reasonable money from time to time. What other guns and models am I missing or should I consider?
