I grunted at a bachelor group of bucks on Sept 20th (a month ago) and 5bucks and 2 does crossed 400yrds of wheat stubble to come into my decoy buck to check him out. All I did was ONE territorial grunt to get their attention, they saw my decoy, and made a bee-line for our stand. My wife stuck an arrow through a nice (rough taped to 130class) 8pt buck.
