So,

I am going on a Kodiak (Afognak Island) brown bear hunt in April and have decided I would use this as a good excuse to get myself a .40 cal rifle. So, I was wondering what model, make, and caliber guys who own them think? Right now I am leaning to .416 Remmington magnum but I would consider .416 Lott, .416 Weatherby, .458 Win Mag or others.

Savage, Winchester, Remmington, or Weatherby are all options.
