I started rattling whitetails in WI in the late 70's. Only while bow hunting. I had better luck in a tree stand rattling while bow hunting. Watch the wind. Start rattling by tickling antlers together. A few times every 15-20 minutes or so. Then after an hour or so try rattling antelrs with more force. Rattling for me based on years of records worked better pre rut or beginning of rut. The more mature bucks came in during mid day. Be prepared for bucks to come charging in. I have used a buck decoy in conjunction with rattling and works well with more open areas like ag fields edges and clear cuts, swamp edges.
Rattling and grunt tubes used to work 20 to 30 years ago. Seems to have lost effectiveness since more and more hunters are employing this method. In fact think more mature bucks are conditioned to be cautious when hearing rattling these days. No w I hunt the rut looking for and locating does and doe bedding, feeding areas and use rattling as a back-up
