when i start out i just tickle the horns and wait about 10-15 minutes. nothing showing up ill give a little more until all out rattling. i had some does about 120 yards away that when i rattled they took off but they came back 10 minutes later. but the next night i watched 2 bucks fighting for about 10 minutes. they would lock up for about 1 min or so then circle and did this over and over. there was a hot doe close by and they would sniff where she just peed then back at it again. only thing that stopped was when 2 other bucks started fighting in the woodlot and they took off to see what was up. i rattled in the biggest buck a real nice 8 that came out of standing corn to 40 yards after i threw in a snort wheeze and he responded immediately. he was definitely a dominant buck in the area. he was 4 1/2 yr old. other wise i think the snort wheeze would have scared him off. if you snort wheeze at a 2 1/2 yo they will head for the hills.
