The whole central portion of 231 is routt national forest, so land access shouldn't be an issue. If your hunting late in the season, i'd stay lower in elevation, 10k ft at ripple creek is most likely too high for the elk later in the season, especially if it has snowed.
good luck, routt and white river are nice areas, some areas (like trappers lake) south out of 231 have been hit hard by fires in recents years.
I hunt 231 every year actually. Mostly for elk. Last year I got a big 6x6 bull. Just got back from up there yesterday. Got another good size bull but it is just a 5x5. Not bad though because I'm in it for the meat mostly. As far as deer go, I have seen some monster bucks up there. Just not a real fan of the taste of deer from the hills compared to deer from the plains out in the eastern Co plains.
Anyone who shoots a sabot bullet has had the problem with loading the next round with a dirty barrel we have all struggled with it.
Between muzzleloader shots I have done some research and testing on my own to find out what works for me for the next shot. I have been using a product called bore butter and when the muzzleloader is just sitting around I leave it caked in the barrel for protection. Have also found that if I lube my sabots with bore butter they really slide nicely down the barrel....
