I'm with Davidmil, a lot of posts in this thread are BS. I've been hunting for 41 years and have heard the snort-wheeze 2 or 3 times. One of the times I caused it by grunting at a very big buck (170s), however, a doe came out and sucked him away from me.

Although I haven't ran out and bought this call, I may eventually. I believe that it may be effective during a short period during the season but now is not the time. They're all fought out and ready to drop their antlers (in my area anyway). There will still be some breeding taking place, a few fawns, but there won't be any fighting over them. By now they all know who is king of the hill. I've witnessed this over the last 8 years.
