as a matter of i have heard a buck growl. it was this buck in the picture, that was the very first timeI heard it. The sound will stick in my head for the rest of my life. I bought buck growl calla few weeks and again watched the video that came with it. The same one thats online. For thoes of you that have actually heard a buck growl, you knwo what im talking about. Remember this new call is the first new vocalization out in a call in 20 years. MAD knows what they are doing when it comes to reproducting sounds. Heres the buck that I shot while he came in growling, not grunting theres a real big difference.
