RE: 270 load for moose
I was going to say with this or for that matter with any number of other bigger caliber rifles with more power, stick with on of the excellent partition or bonded core bullets (e.g Nosler, Hornady)165 gr.
I've been told by an old Finlander, as lately as this morning, by a fellow who while stationed in Alaska in the 50's hunted Moose there. He said a double lung shot that carries all the way through will take a bull Moose down. He took to big bulls that way.
I think a couple key things are that the bullet needs to hit with enough force with a bullet that'll retain most of it's original weight both to take out the lungs and through and through to bleed it our faster. A Moose needs the big lung capacity to go through what they do. Take that from them and they will come down.
