LAST EDITED ON Nov-15-10 AT 07:12AM (MST)[p]Depending on how long the horns are, you can put it in a plastic garbage bag with a little water and then double bag it. put it in front of a heater for a couple days and they should pop off. With a trophy like a oryx, I would look for someone with beetles in your area, boiling ruins the bone and you always run the risk of it falling apart.
If the horns are to long, wrap them up with saran wrap, black plastic bags, then put in front of the heater.
