Well...............
<br>
<br>The 340 certainly outperforms the 338. But then the 338 ultra, outperforms the Wby, and of course the 338/378 weatherby outdoes the ulta..........then again if you took a 50 BMG and necked it..........Oh!!! sorry, sorta lost my head.
<br>
<br>The Weatherby offers more velocity as do the others but the price in ammo costs, recoil (yikes) and related aggravations would not be worth it to me. You (can) use calibers like these for lots of things, and they (will) work, but if you have other choices, I don't see much usefullness in Baja Alaska.
<br>
<br>On the other hand, if big and bad is what blows your skirt up, these are all in the baaaaadddd category.
