JFYI, if you could not hit a 320+" bull in 40 with a wrist rocket you have no idea how to hunt elk. It's not about big bulls being available there, it's just about dudes putting in the effort to get where they are and navigating the private. I've spent enough time in the unit on public to know I'd never punch my tag on less than a 340" bull there. Of course most guys will shoot the first 320" bull they see and be happy, but there are enough toads in there to take your time.
Funny story... I took my son on a 2nd season dear hunt in there when he was 16. We are both mostly elk addicts, so we got all fixated watching and listening to multiple big bulls scream and fighting one morning on public. We watched one bull we nicknamed 60X60(you figure it out), but he was all broken up. Later in the AM after looking over many GREAT bulls we heard a rifle shot and then worked back that way. There was biggerstaff with his client. He shot that broken bull. Not sure he or the client loved it when we told him how long we had watched that bull, but all the really good bulls were the ones we watched a little farther up
