What's your price range and what do you want? I always wanted an original, pre-64 Win M70 in 375 H&H. However, if I was going to get a 375, it would be foolish not to get the 378 Weatherby, right? Why give up several hundred fps, right? Is a 460 Wby too much?
I think I would put a Sako action on a Hart barrel, sink it in a really nice Weatherby stock and chamber it for 378 Wby. I would top it with a Ziess scope in a 3-9 or 10X.
Problem is, I have a lot of other wounds where the money is bleeding from these days
