"I agree that all shooting is good practice but being proficient on the shotgun range doesn't mean you can shoot a 40 on the silouette range or visa versa."

I couldn't agree more, but you won't forget your second trigger if the shotgun you shoot has one too. And you won't be hunting for the top lever either, or trying to find that sliding tang safety, and if you load from a belt on the range it won't be unfamiliar in the field after buff or elephant. I'd bet on the fellow who does quite a bit of shotgunning, as well as his share of rifle practice, when it comes to putting a second shot into anything running.
