From what I've read you don't boil it hard as that will cause cracks. I've read quite a bit about skull (European) mounts and the best method concensus seems to be scraping as much of the meat off the bone as possible, but don't actually leave marks on the bone, do it gently. Better to leave meat than damage the skull.

Then submerge the skull in clean water. The trick here is to allow the meat left ont he outside of the bone, and the meat inside the bone, to rot slowly. This is less stressful to the bone and will prevent cracking the bone. It'll take a while and may cause a smell, but the old timers seem to think this is the best way. Change the water out every so often. I think this may take a few months.

Once all the meat has rotted off the bone it's time to take it out and use insects to finish. Like someone said beetles are the best method, but I've heard ants work well too. Just drop it in a fire ant bed and leave it a while. The bugs will not only eat all the meat on the outside, but go inside and eat the brains, membranes, and stuff you couldn't get to.

Then you do the peroxide thing.... I'm gonna try it if I can ever get a little buck again... Bad year this year.
