I practiced on a small antelope last year. Just let the head rot a few days and keep twisting around on the horn sheaths. They eventually popped off from the decaying process. Hit them with hot water and then let them dry out. No damage and worked fine. Then let skull do its thing like any other one. I wouldn't hesitate to do a big antelope using that process.
Ackleyfan, that is one seriously big looking antelope, congrats.
Thanks,
Pretty much the exact process I used on this antelope, I put it in a black garbage bag in a plastic feed barrel for 3-4 days in the summer heat and the sheaths will just pull off, then put the skull back in a 5 gal bucket and soaked for a couple weeks then I degreased in dawn, and then I sprayed with 40% HP!
I bought a tank heater to speed the process on the next ones after reading this thread!
I think this maceration process turns out very good results
