I am using a Flextone grunt call that makes mature grunts, Young bucks, Doe grunts and Fawn right now. I just dont thing that this call is loud enough to be herd farther away. There was a 140 class buck running past me about 70yrds away and i grunted about 10 times and he did not here me. Can you guys give me some pointers on what calls and that you are using....and if they are working or not. Thanks a lot.
