LAST EDITED ON Jun-21-15 AT 12:15PM (MST)[p]It's always great to have a buck lined out for opening week; however, that's when about 85% of the hunters are in the field. If the season opens on a weekday it may not be as busy as opening on a weekend. Some units are super large in size and hardly have any tags issued...so hunting pressure may not be an issue. Obviously you have the pick of the litter if hunting opening.
Smart ole bucks generally have a knack for making it through a few hunting seasons. It can be super warm in Sept and it is nearly impossible to glass and field judge accurately... other than a few hours with all the heat waves.
A lot can change from one unit to the next. After the first deep snow antelope in some units may start migrating...some to adjacent units. It obviously helps to know migration patterns (if any). If you are hunting a unit where antelope tend to migrate into for the winter it may actually be to your advantage to wait. Obviously if there is no snow in a particular year the antelope will be scattered more than a year with early, deep snow.
It's aways nice to hunt the rut but antelope usually rut in most Wyo units until the first or 2nd week in Oct. After that time they often join up in winter herds. It's nice looking over a pile of bucks but it also can be tough stalking into rifle range when there are 20 to 200 eyes watching you. Sometimes smart ole bucks come out of secluded locations after things settle down a couple weeks after the season.
Late season antelope capes are pretty impressive! A lot of guys have never waited until mid to late Oct to harvest a long, thick haired caped buck...they are actually pretty neat! Most early Sept capes are super short haired but still have striking colors.
There are quite a few scenerios that a lot of guys never consider. With all that said, there are both advantages and disadvantages to early vs late season dates.
