It seems rattling differs from place to place. Much of this is based on buck to doe ratios.
When you have a low B/D ratio they seem to come on the run... conversly when the ratio is high, i.e. way more does than bucks they seem to not respond as well. Most of my experience has been during late pre rut and early rut here in IL and Texas. I have had bucks actually put the breaks on so hard that they threw sand on me in Texas...
I would suggest as Friend said a light "twitch" of your horns and then wait for real early season. Not like the full out beat your hands, ground tree and ground pounding along with snorting that works later.
