The difference I have seen between deer and moose - deer will jump when hit, and try to run away. If well hit, they won't make it far, but I did, for example, have an 8-pointer go about 100 yards with the heart completely gone. With moose, other than the one I mentioned above, I can't remember ever having to chase one. I have, on several cases, seen them just continue walking, take a step or 2, and lie down. But again, this is just my personal experience, and not a scientific conclusion. Another thing I noticed over the years - deer are always extremely alert, ready to bounce, like a wound-up spring. Moose are more like Pa Kettle (for those old enough to remember) on Valium. Again, is my observations, and there are exceptions.
