You're right on the mark about the gateway aspect of shotgunning: First it's a bargain pump, but you can shoot it good enough to get hooked. So, you buy a reloader so you can shoot more. Then it's an autoloader to shoot better doubles. Your scores go up with the autoloader; but, it's a bigger bother policing your hulls than the pump was. Next, you find yourself with a reloader's dream, an O/U. After the newness of the O/U wears off, you realize that you'll be shooting even better if you get higher grade O/Us specific to each of the shooting environments. You're on top of the world in all environments; but, then, you realize that there's a world beyond shooting just 12-ga... so it goes.Now you need to know that a good fitting 12 ga is like a gateway drug to shooting more. Then you will get tired of picking up your shells, and then you will want an O/U. I'm just saying.
