RE: Late Season-Calling,Rattling?
Whitetails continue to search for hotter does into January. In areas where the buck/doe ration is good, the rattling can be effective for quite some time.
I've rattled in 5 this year but no shooters.
As far as grunting, the short grunt, which is about 1/2 of second long and rather quiet is effective year-round.
One of the main reasons I love hunting is that I love calling in whitetails and turkeys.
Hit the horns, use the grunt call... it beats sitting in your stand and praying "Dear God, please let a deer walk under my stand!"[8D][8D]
