I don't know much of the science behind rattling, but sometimes I think that there's little that scientific about it. I have had great success with it in years past. I had four seasons in a row where I killed decent bucks by rattling them in. There was no mistaking their approach in response to the horns, either. They literally came running in. One morning I rattled 5 bucks in at separate times within a 1 1/2 hour period. I personally think the buck:doe ratio and the timing of your calling has the most impact on response. The more bucks around, the greater the competition, the greater the response. Rattling during the 3 weeks prior to the rut has been my most successful time. I usually rattle for about 45 - 60 seconds, and I typically rattle as loud as I can, with varing vigor. The further the sound carries, the greater the chance it will reach the ears of an eager buck.

That's my approach. Like I said, I don't think it's as scientific as some may claim. My grampa once shot a buck while sitting around a camp fire after it ran toward the sound of him blowing his nose. I'm sure there are many rattling methods that will work. Being within earshot of a buck is the most important factor. No buck, no response. However, no rattling, no response either. Gotta give it a try.
