Have a look on the Woodsman / 3Rivers website and you'll find plenty of examples of moose and other big game animals taken by the Woodsman. I've only taken two pigs with them. Will they work on moose? Sure, it's been done more than once. Are they the best for moose in the event of a serious bone encounter? Possibly not. I have a bunch of Woodsman-tipped arrows which I hope to put to good use on feral game here in Australia. So I am definitely not anit-Woodsman or anti-3-blade. I've had some awesome experiences with 3-bladers! But, I must admit to being anti-advertising nonsense, and that I wasn't impressed when I read (or heard) the advertising rot about the Woodsman being the deadliest broadhead in the world, and that no big game animal is safe; because that's such a big statement and it includes elephant, buffalo, hippo and similar which one would be foolish to tackle with a Woodsman. Moose are one of those borderline animals...the Woodsman might or might not work, depending on the circumstances (which can be said of any broadhead, admittedly, though I maintain that on larger game certain heads will be more likely to bring success). So, there's two-bob worth from a fellow in Outback Australia who's never seen a moose, but has taken a few animals that size or bigger. All the best to you, Woodsman or no!
