That is definitely going to be an epic trip! By the way, welcome to the forum.
So what rifle(s) are going to bring on the trip?
I've settled on my Tikka T3 in 7mag with a Z3 BT scope.
I won another trip to Nanuvut with Canada North for caribou and muskox and I'm finding out these "free" trips are really expensive!
I kind of wish I had gone ahead and bought the Borden rifle they had up for auction, but I'm very happy with the weight feel cost and accuracy of the Tikka.
