For me it would be the 340. Fast and flat, and enough juice for really big stuff. One of my wildcats and the rifle I have killed the most game with (well into the hundreds of head of big game, a couple of continents) is essentially a short neck longer bodied 340WBY. 225gr TTSX's at 3100fps are a marvelous combination.

Since I don't have to limit to just one, I also have a 257BEE for deer and similar sized animals. I like that one a lot, too. With the 4 or 5 257WBY's I have owned since the early 80's, 40 or 50 deer at least. Many here have shot more than my number, but IME the 257 WBY is an ideal deer smacker.

LOVE God, LOVE your family, LOVE your country, LIKE guns and sports.
