I once had a 670 Winchester and can say that my experience with it was great. If it were here, I'd have to say that I'd be elbowing you outa the way to get it first.
By the way, unrelated to the 670 that I owned, I have a very nice 670 Win. 30-06 barrel you can get cheap, if you decide that you just can't stand the word "Sears".
Good luck,
Bob
