RE: Calling late season deer??
I am a deer grunter.. that is to say I call deer or attempt to call deer throughout the season here in Illinois. There are very few occasions I do not call.
That being said, during the late season I really only call when a deer is in sight. I no longer call "blind" as I know deer are already pretty pressured at this point of the season. Reading the body language is the best advice I can give. A couple of bucks traveling together.. I'll grunt softly (just enough for the deer to hear) say 2-3 times. Followed immediatly by a soft doe bleat that drags on a bit. (I use the truetalker).
A buck that's by himself, feeding with a relaxed disposition. I like to get more aggresive.. Grunt, bleat, Grunt, Grunt, bleat......follow the buck's lead...then snort wheeze. I've called in many late season bucks this way, but scared some too. Hope this helps some.
