Because you'll likely not be shooting beyond 200yds you need not worry about which bullet is the most accurate just pick a tried and trued one. And, in my not so humble opinion that would be the 140gr Nos. Partition because I don't like surprises. If it could be cold during your hunt, pick a powder that's temperature insensitive such as H4831. One last suggestion, because you'll be hunting thick stuff shoot to break the animal down if you can. Good Luck!
