Depends on the terrain. Some say out to 300 yards some say out to100 yards.Terrain and amount of cover for the sound to travel through plays a very big part on how sounds travel.
Depends alot on wind also cause it never quits blowing here in the Midwest. The only deer I ever rattled in I never saw coming because he came in behind me and was 8 yards from my tree be4 I seen him. I shot him be4 he saw me too pretty exciting if you ask me.

I pulled two bucks in from 150-175yds this year but it was in a cow pasture / hayfield. I also got one's attention at 200yds but no response other than looking my way.
