KW: The 338 RCM is NOT one of the choices in the question.
IMO the RCM doesn't offer enough advantage over the Federal to choose AS you did, I pick 338 WM as minimum ALSO not a choice.

It offers enough advantage, especially in a short, handy rifle, that I'd take it over the other two in a heartbeat. Alas, as everyone's quick to call foul, it's not a choice.
That being the case, I'd likely follow the Keitheian hypotheses and opt for the bigger hole.
