I just posted, Saturday AM I did a light "sparring" rattle with the rattle bag & a few "young buck" grunts mixed in. Had my 7 pointer come in with in 10 minutes. I don't know if that's what brought him in but he didn't have a care in the world except looking around for the fight. 3 years ago on opening day of SZ, I saw a buck about 100 yds out. I did a few tending grunts & he came running. That's the only experience that I can say were definately attributed to calls.
I wouldn't start with deep, dominat or tending grunts yet, More young buck grunts & let the old boy come and set the pecking order straight.
