Rattling and grunting CAN be affective anytime after the velvet comes off. You will seldom get a buck charging in to one of these calls early in the season though!!

Just keep it short and sweet in the early season and experiment a little. I dought you will run anything out of the woods.

I grunted at a 172" buck, eight times Saturday morning, from 35 yards and he never even raised his head.
