Last Saturday I had over 5 bucks come into my decoy and I had it set-up as a buck. However, none of the bucks were shooters, but one was border-line. My friend used a decoy also and he had a MONSTER 13 pointer come into his decoy, but needless to say the outcome wasn't what he wanted it to be (long story). I would advise you to use a buck decoy. Those big bucks will come in running! Espescially with how much luck other people have had on this site grunting and rattling bucks in. The set-up that I use is somewhat differen then that of HunterMan, but his may work fine too. I like to put my buck decoy quartering towards me, because in my experience bucks come into buck decoys head to head for a fight. Think about it, bucks do not want to smell the hind end of another buck this time of year, they want to fight! Put your decoy 10-15 yards from your stand, quartering towrads you, and you will have an easy shot at a quartering away buck. I agree with HunterMan 100% on the scent spray. Spray that decoy down with scentless spray, and then put some territorial buck piss on the ground around him. Good Luck, and I hope you kill a big one!!!!!
