The H&R Topper in .410 was the foundation of shooting education for both my brother and myself. Gun is still in the family, near about 65 years old at this point and still in good functioning state. It's primary target these days is iguanas and it hasn't lost an argument yet. And ya, I've killed pigs with it. And doves, quail, ducks, bunnies and squill. A bunch of them.
