My personal big bear rifle is a 338 all weather Ruger rebarreled and redone to 458 WM by Labounty.It sports a red dot scope of late.Doubt I would use the red dot for prolonged use in a harsh environment.When the red dot goes the scope is useless.

Although its penetration will exceed a Brenneke slug considerably I really enjoy carrying the non scoped Beretta semi with Brennekes.I can shoot the shotgun 3x before I canget the bolt down for a second shot on the 458.

What would be the Ultimate NA/Alaskan bear gun for harsh environments?
How about a 470 or 500 NE stainless Double rifle with synthetic stockwork? GAG!! Would that not be an ugly thing? But it would get the job done repeatedly with the most reliability.

I hereby volunteer to test such a gun if any manufacturor would actually consider making it!!
