When you say loud calling do you mean highball or just loud chuckels or loud feed calls. I just want to be clear on what was consitered loud. What was the weather like that day, if the wind is blowing hard I will blow the call untill the birds are in easy shooting range. I have had ducks come in and land when 2 hunters are highballing at other ducks that are still way out. The biggest key to calling is watching the ducks reaction to the call, this will teach a hunter when , how loud and what sound to make.
