I've rattled in by two biggest bow deer, Nov 1st and Nov 3rd. Earliest I've rattled in a shooter was Oct 25th. I've had great success rattling and have had many days where I've rattled in 10+ different bucks, the most being 16 bucks by lunchtime in early Nov of 2006. Many were 1.5-3.5 yr olds but I occasionally rattle in mature deer, often after I see them at a distance. My best rattling spots are way back in big private timber on saddles, I doubt I'd have that kind of luck on smaller parcels or public ground.
