not to start anything ; but I have heard the ratio thing all my hunting life and that is a good while.
where I hunt there has not been a lot of does taken,I mean you can see 20 does to 1 buck.I think that is way out of wack!
to get to the point ; I take 2 to 3 bucks(good bucks) a year by rattling them in(close)15 to 20 yards most of the time.it is late bow season and then B/P season is when most of the rut is where I hunt.
Morning , evening , anytime I can get off to hunt.I got off at 3pm on one hunt,was in my stand by 3:20pm,started to rattle,in less than 10 min. I was dragging a nice buck to the truck.I took another one from the same stand the next morning,the wife watched both hunts from her tree.

so I think if you are close enough for a buck to hear you and you don't beat the horns to death,you have a good chance of a buck coming to just see what is going on.
When I rattle , I just tickle them as it is called,maybe it can be heard 100 yards if it is calm.

where I hunt I like to hear the other hunters say we have to many does for the rattling to work.I just set and smile and listen.go to my stand and get out the horns.
