They are built like a spike elk,i wouldnt go any smaller than a 30-06,you can hunt them in Alaska without a guide,all you need is to hire a pilot to transport you to a basecamp along the migration route,would save you a bunch of money.

Thanks for the reply, do you happen to know of any pilots whom I may contact?

Rusts flying services in Anchorage.(flyrusts.com) good place to start.

Thank you.

By the way have you ever used his services?
