My sister is 5'1" and about 115#, and she shoots skeet with a 20 Guage, semi auto. I think its a Mossberg. Brand shouldn't matter that much, if your looking for price and guage as your main criteria. Do you want a pump, semi auto, over and under, double barrel? I don't shoot clay targets like my sister, so I don't know which type of action is preferrable. The NEF Pardner pump is very affordable, and 20 guage is probably fine. Other than that, you probably just have to shop around.
