My life-long approach to beginning shooters, especially children and small-framed women, is to down load 12, 16, or 20 gauge to 1/2, 5/8 or 3/4 oz of shot. This opens up choice of guns greatly, often resulting in a much better handling gun than the average 410, and often allows beginner to stay with same gun for a few years. I and those beginners have killed plenty of birds, rabbits and squirrels with those loads.
