I'd take the muley , hands down ! Every year 400 class elk are being killed , and found , seems theres a few states that are really growing em big , but less and less monster mule deer. 200 in typical , wow , those are some big deep forks ....
Have found sheds off of several 200+ inch bucks over the years, so I'd go for the 400 inch elk sheds hands down. Not a lot of elk in my shed hunting areas, so I'd be stoked to even find a 330 inch bull.
I would take the deer, I have a few sets of 400 bull. They are becoming alot more plentifull. Only have one deer set 195 3/4 and 2 sides from different bucks around 70-80 per side.
you have a FEW sets of 400+ bulls. What state are you in? you must have a pretty nice little spot to be finding those. do you have to compete with people for those?
