Try the snort wheeze. Western PA, October 18th, I had an 8 point buck walk parallel with me at about 50 yards. Not wanting to spook him so close, I let him walk into the cornfield he was heading to. He had to cross a grass opening to get to the cornfield. When he did, he was out at around 120 yards. I snort wheezed one time, he turned and looked in my direction, then JOGGED to 20 yards from my stand. I decided not to shoot because he wasnt quite as big as I wanted him to be and he continued on his path back behind my stand and on his merry way. I could just barely see him with the light fading so quickly and he was now 80 yards behind my stand. Just for giggles, I grunted twice. Within two minutes he was back under my stand at less than 15 yards. This time he checked the area hard, and then continued on his way back into the cornfield.
That was just one encounter I've had with the call.
