I have been grunting with no success until yesterday. I had to work so I got to the stand at 2:45pm and once I sat I grunted 1 time then 10 minutes later I grunted once more then this 5 walked out. I'm not one to shoot a 5 point most of the time but I had to break the buck ice this year. The only shot I had was a neck shot which I never tried before and now I am a fan. I got down and drug him under my stand got back up and 2 big doe walked out so I picked the biggest and dropped her also. I think I figured out how to grunt call after this. I have been grunting every 10 to 15 minutes in a series of 3 or 4 grunts with no success. I think the key now is to only hit the call once every 15 to 30 minutes. That was the first time it worked so it's a work in progress but it was way cool.
