Always been in awe of the .340 Weatherby, ever since I first came across the cartridge 40-some years ago. Never had one, though. Always went for the .375 H&H instead. But, were I to acquire a .338 (something I have long wanted to do), I'd almost certainly go with the Winchester as it is readily available in rifles at a cost I can afford (it is shocking what some .338 Win Mag rifles will sell for, used, much less than some of the more popular calibers such as a .300 Win Mag...you've got to look but they are out there). The one .340 Weatherby I might be able to afford is a Vanguard, assuming that it has been chambered in the cartridge.
