I was started out with my uncle's Browning A-5 20 when I was about 7, only cause then I was as big round as tall and I had the mass to handle it. This was a wonderful time in my life and one of the worst hunting mistakes ever made. Every time I saw a dove it was BANG-BANG-BANG. And no bird. I think a single shot should be used or even the same gun I had with the magazine cut-off on. However, I strongly believe that a child should be in the field with an unloaded gun for at least a season and told what is done right and wrong. As a result, or just my excuse, of having all 3 shells at my disposal as a child in a dove field I am still a bad shot with a shotgun, however, I grew up shooting squirrels and rabbits with a single shot BB gun and had to learn to feel the shot at a young age, now I am a much better rifleman than a shotgunner. Like Pa always said, "Good roots make a strong tree."
