In case you didn't know the ivories are the lone teeth located on the top and they sit foward off to the side. If the elk is a young one they will be hollow. I couldn't answer your question on the meat guy as I have never used one. Good luck on your hunt and fill that tag.

One more thing, If the elk is a bigger one, look inside the cavity up where the heart and lungs are you will find two strips of meat on each side of the spine. Pull those also, these are called the mock tenders. They will be about the size of a deers tenderloin sometimes( if the elk is big enough) these would look good right next to your mashed potatoes as well.
