what kind of clays will you be shooting? competition? if just for fun and for hunting, try out a winchest 1300 youth ranger in 20 gauge. i think you will find the stock and forarm are perfect for your size. the stroke to cycle a shell is pretty short to so you will most likely find it comfortable. if competion and hunting, go with a semiauto. beretta makes a nice semiauto in youth. but for the money the winchester can't be beat for fit on a small shooter.
