RE: big buck tactics
#1 you ain't gonna get him to get up and start moving during the day. He is smart enough to know that days are dangerous - that is how he got old and big. He ain't no dummy.
I recommend you figure out where he beds, sneek in best you can. He is most likely only active in and out of the bedding area very early in the day or very late. You have to watch the wind! If it ain't right you either have to have a backup plan or just simply don't hunt that day. If you want HIM you will have to be willing tomake some sacrifices like that.
If he feels you are pressuring him or he gets suspicious - he'll be moving on.
Good luck.
