Unless your buck to doe ratio is really good rattling is useless. Ive brought in deer using the primos estrus can, primos bleat can, and true talker grunt call. Ive also spooked them. You have to be careful and not over do it. I usually will call three times and wait fifteen or 20 minutes and call again. If nothing is happening Ill stop all together for awhile. During rut Ill do estrus call about three times, grunt call three times or so and then wait. Doing this and using code blue estrus scent trail and scent wick hasnt failed me yet.
