If you watch any of the hunting shows, it seems like they mostly use rattling horns to draw them in.
My father-in-law and his buddies do use grunt calls...but if you don't know when and how the deer grunt, then you will just end up running them off.
I have only been hunting for 4 years. My first deer was a 13 pointer that I got on my second day of hunting. Total beginner's luck. I wasn't even where I was supposed to be at the time. (damn near had a heart attack...and I have been hooked ever since)
I haven't been using anything lately, and to be honest...that 13 pnt...is the only for me so far. I have had a few young bucks in my sites, but decided to let them go.
