I usually rattle most toward the end of Oct into the first 2 weeks of Nov. In the first week of Nov, I'll start using an estrus bleat and will follow it up with a tending grunt while swinging my head-- trying to sound like a buck dogging a doe.
This year I rattled in 4 bucks. One was 170's with a 10" droptine hanging off his left beam-- biggest buck I've seen from a tree! Just couldn't pull him in. He hung up at 45 yards looking for the fight and snort-wheezed 3 times trying to "call me out". He finally turned and walked away... but there's always next year.
