I have a little time to type this in now so here it goes:
I have mentioned the moon and the how we could see an early rut. Others have mentioned dates and times that they have been successful but really it depends on the phase of the rut we are setting up to hunt.
I will steal from Charles J. Alsheimer because I respect his work.
The Seeking Phase usually occurs as the rutting moon approaches, testosterone is building in our bucks and they are looking for does coming into heat. Rubs, scrapes and other activities become almost feverish. This is one of the best times to be on stand.
The Chase Phase not to be confused with the Seeking Phase has some overlap but the huge difference is our bucks start to look like cutting horses, they are chasing does down almost trying to herd them. The full or rutting moon is in place and its usually 2 or 3 days after a full rutting moon. This can be a difficult time to hunt because the action can take them out if range.
The Breeding Phase is what gives the rut it's name. Does are in heat and will accept a bucks company. Scraping usually ceases and activity actually slows down. It usually begins 7 days after the Rutting Moon and usually lasts a good 2 to 3 weeks. Now, this will stir you all up, this can be the most difficult time to hunt. Does move very little. Strategy has to be to sit in doe's core areas where the breeding takes place.
The definition of a rutting moon is the second full moon after the autumnal equinox and this being one of the main triggers for the rut.
So, in conclusion, if the rutting moon is October 19th this year, and the 2 or 3 days leading into it are the best on stand for overall activity, what does that do to our thesis of hunt Halloween until Thanksgiving?
Crazy, just a FYI that I am studying.
Also, in my opinion it depends what phase you are trying to hunt to kill a mature buck!
PS: last year was early too according to the moon, I saw some difference but November was still and always will be the main month.
