378 Wby is the ticket. Why muck around with weak stuff like the 300 and 338 WM’s...
378 is too fast, the bullets just pencil through.

I'm going to amend my answer... 416 RM is the ticket.
Then it just comes down to whether you want a 350 gr mono or 400 gr Partition. But that's an entirely different 12 page thread...
