A recent email referred to one of these in 458 win mag. I haven't seen any and can't find it on the company website. Has anyone seen them, shot them or know how much they are? Thanks.

As far as I know they've never chambered the classic stainless in .458. It would be pretty easy to rebarrel a 300 win mag or 338 win mag to 458 though. I'd suspect that if someone is selling one of these then it's a rebarrel.
