I wonder how many people who voice an opinion have actually killed a moose, or even packed one out?

The thing is, a .270 WILL kill a moose, without a doubt. The other thing is, it takes a lung shot moose about five minutes to bleed out and die. In that five minutes, that 1400 lb moose is going to go where they always go when they get in trouble -- WATER!

You are going to have a bugger of a time breaking a mature bull down with a .270 if you need to in a hurry. You may have one shot to get him down FAST. Personally, I would bring an .30-06 or larger.

Just as an afterthought, a co-worker of mine used to guide up here. One time, a woman client refused to shoot anything larger than a .270 on a grizzly hunt. He was young, and against his better judgment allowed it. She got her bear, but it was pretty bad on both him and the bear. He calls that one of his dumbest mistakes ever as a guide.
