I got my first deer 3 yrs. ago using a grunt. A 4 pt. buck was about 80-100 yards out. I grunted at him and got him to look my direction. About every 10 min. or so I would grunt again. After thinking he went in the other direction,I gave up grunting for a little bit. Then I caught a glimpse of him coming up out of the ravine in front of me at 40 yards. Nailed him at 20 yards. Like fletch said though, don't go crazy. Don't be surprised if you have a few catch you off guard. Good Luck
