D13er gave you the right answer. You can choose which list to enter the buck, but it will not be listed twice. Just because the buck is ranked #247 in one category, or #230 in the other category, shouldn't be the driver for your listing decision. (or whatever the ranking may be) Personally, I would make the decision based on the primary characteristics of the rack. Is it mostly non-typical, or is it primarily a great typical
If you want to make a change to the listing, contact Justin Spring at B+C headquarters in Missoula. I'm not saying it can't be done, but it seems unlikely to be worth the effort. Either way, you have alredy honored the animal by listing it in the first place. All the rest seems more to be focused on rank, awards, etc.
