I am moving to Alaska, and have heard that I need a big bore rifle. I have also heard that a 30-06 is just fine and I should use that. I plan on having a bear gun with me at all times anyway, but what is a good gun to get (I am looking for Moose, but want to be able to use it on smaller game such as deer, elk, bu also)?

On a side note, I love to shot for fun (targets), so something with reasonable ammo would also be nice, but if impactical so be it.

Thanks for your help.
