Thanks, Mr. A.H. Fox XE --not too shabby a choice in a high grade American Boxlock gun on your part--Highest grade Fox double ever in my hands was a 12 bore CE, and I was "smitten". No, sorry to say, I lost out on the bidding for this older M70-and IMHO, the pre-WW2 M70's (and other Winchester firearms as well) are the "best of the best" ever made. I stopped my bid at an even 2K-mainly due to the threaded muzzle break device--it went for $2500 and sales tax. C'est La Vie. But I do agree with you 100% on your choice of a "stopper" rifle for Alaskan Big Bears (are there any small Alaskan Bears?--I have a 1940 era M71, a gift from a childhood neighbor who hunted in Alaska and Alberta--I know the .348 somewhat, but am not familiar with the 450 Alaskan Cal.-- I'd probably opt for a Mauser styled BA in .416 Rigby- express sights--"use enough gun"!! words of wisdom indeed.
