John, Your outfitter was quite correct. Even large moose are not that hard to kill. The problem raises it's ugly head when you are forced to protect yourself from a "big Fuzzy". When shooting a big Alaskan moose, give thought to how far from transportation is this monster. A couple of years ago a friend dropped one that was about a mile from where they could land a plane. 12 trips later, he had to face off with a bear when he was finally packing out the rack. He was a 68" monster. "Be prepared" It's the Boy Scout's marching song." For over 40 years, I carried my .375 H&H when I walked among them. Then when winter came, I carried my 7x57 AI. Shot a couple of late season Moose and lots of Caribou with that gun. I used 160 gr. NP's.I have hunted Alaska 8 times. Taken moose and caribou and been party to many others. The outfitter requires 338 win mag minimum as there is a large brown bear population in his units. I used Hornaday 225 on all of my animals. They all were down in a step or 2. My largest moose measures 72" cured out, I shot it at 20 yards. The biggest problem with a poorly placed shot is you are not the only one tracking it in a short period of time. Meeting a bear while dressing or packing an animal gets ugly fast.
