One thing I didn't mention that I should have. Avoid the shoulder period. Lung shots or a tuck and tickle quartering away shot in the pocket. Getting through the ribs to the lungs doesn't take a whole heck of a lotta juice. Getting through the thick hide, muscle, and bone of a Moose shoulder is by far another story. Be as wary of your shot choices as you were when you were Bear hunting last fall and you will be fine.
