There's a few locals that if they drew the tag it would be 330"+ or bust but I still think you're going to be hard pressed to find a few killable bulls that big unless you got some local info/help. That country is pretty damn wide open on the breaks and the big bulls get picked over HARD during the first rifle season when they are still herded up. The IDFG has more than doubled the bull tags from 3 years ago, added a 2nd season, and done all sorts of things to help kill off the mature bulls in that unit.
IMHO 300"+ = shoot. If you don't think another hunter will find that bull you have a good chance of finding him in the same spot later on as the big bulls should be holed up in a knarly canyon somewhere recovering from the rut...
Good luck and post pics!
