Most of the hunters in my lease use daylite and dusk feeders or the timer type feeders and they have a ton of 1: am pictures of big bucks photos.
I use homemade bump feeders and the deer still feed during the major and minor feed times. If that falls during shooting hours I see them.
Now that being said, I can't say if its because the feed is there when they want it or if it's because the does are feeding so the bucks follow.
