Can call is great but I've had more luck with a small primos adjustable call that goes from distressed deer to big buck grunt but it seems to work best with doe bleat and I called in two bucks the other day with it and shot the six point as the other one was not in range and I never see bucks in this spot, well very rare .
Rattling antlers or one of those plastic rattler gizmos works good.
I have the bag of Lincoln logs to rattle with.
