Rod,
I raise bucking bulls...So I do know a thing or 2 about hot cattle. My cows are worse than my bulls most of the time because they dont get handled as much. From experience if you have one that is hot and want to calm it down some it can be done with time. I get in cows that are bred to the hilt and very good producers that are hotter than heck. I turn them out with rest and hand feed them everyday, even a small amount in summer to keep them coming up. Make sure to overdo anything you do, make noise, talk out loud, whistle, whatever to make noise and settle him where he does'nt pay it much attention. It can take a while but it can be done. It depends on if you like him that much.
Also though, like someone said before, he can also pass it on, I know this because I breed for the trate myself. I also see you are from NW Arkansas? There are a lot of rodeo stock contractors around there. I dont like a brangus bull much myself, but if they are made right they can be good sometimes. Might want to give one a call and see what happens instead of taking him to killer and getting $700 for him tearing up everything. He might be worth a bunch, never know, he sounds like he ahs the attitude anyway. ;-)
