Did it once, I shot a 7pt high and broke its back. I pulled out my knife grabed the horns with one hand and cut the throat, as soon as the knife poked him, blood was blowing out of its throat he thrashed his horns i had to really hang on not to be gored. When i finally let let go you could hear him drowning in his own blood. It was the fight of hanging onto the horns i don't want to have to do again.
