Friend of mine had his daughter draw an antelope tag in there last fall. They saw tons of deer but not any elk. From what I understand they shut down the roads and it is horse back or long hikes in to where the elk are. I have been keeping an eye out for more info on it also. Good luck. Usually the limited permit areas in Montana that have good draw odds are not all that great. We have so few limited entry permit areas, you would think if the potential was good the odds would be harder. 455 is a large peice of public ground that is wintering ground. So I think it is managed more for restricting amount of hunters more than trophy potential.
