As almost everyone on here knows whitetails are interesting creatures. The same deer will never react the same way twice, but at the same time the same deer will always react the same way twice. With that said I used the Buck Roar this year along with a Delta decoy. I had the 11 pointer I shot this year come stomping in from 100 yards to within 20 yards of me and the decoy. He wasrubbing trees and grunting with every step he took.At this time the rut was winding down somewhat but this big guy knew exactly what the Buck Roar was saying. With that decoy he never even looked at me even when I moved a little to get the gun in a better shooting position. On a different day he might not have even came to the call so you just have to be out there as often as you can.
