My two cents, is I'd have a trip planned earlier in the year. Couple reasons include bulls typically lose their horns towards the end of November, depending on snow access to certain areas where moose are might be difficult, in early november there will probably still be bulls rutting a little bit, I shot my bull on Oct 29th and he was in a herd of about 6-7 cows and there were three other bulls around. If you aren't successful you only have one weekend left to get regrouped and make another run at it. Being that it is OIL I'd want to try to maximize my chances of finding the bull you want.
