moose have spindely rickety legs. I would simply knock one off balance and then be upon him raining down blow after blow about his head and body and balls and ballsack.
Yeah okay, you would take a hoof to the head and your body would have the consistency of ground beef after a couple of minutes.
Go to the 44 second mark of this video and pretend you aren't on a snow mobile and the moose isnt a lil guy.
(Warning, video below shows a moose attacking a snow mobiler then getting shot)
