The last buck I arrowed was 160 class 11 pointer last September. I was set up about 45 yards from his bed... Last year in October I shot a 166 inch 10 pointer, I watched him get out of his bed 75 yards away... This is very typical for me.
Both of these bucks would of never left the area in daylight like the younger bucks do... I hunt mostly public land with high pressure, but mature bucks every where have a tendancy to move more at night... Closer to the bedding the better.
However, bumbling around and setting up without knowing where the bedding is can lead to bumping the buck out of there. I usually have these beds scouted out quite well in spring and know exactly where they lay, and what they can see , smell, and hear,. I pick out a tree and an access then, and don't come back till its time to kill... And I never hunt a stand more than 3 or 4 times in one year. Big bucks are awesome at patterning hunters.
