For some reason there are lots of overweight 450-400 doubles floating around. They're fine for the shooting range, but if I carry a gun that weighs in like a 470 NE (10 lbs), then I want a 470 NE.

Last year or the year before Cabelas had a 450-400 that weighed 14 pounds. I think it was built on an 8 bore shotgun frame. They were charging US$1000 per pound for it.
