I applaud your hunting ethics. I have had deer just across the property line that I could have tackled, but I let them walk as I did not have permission to hunt that property. I am glad to hear that you got the buck the ethical way.

It is late for rattling, so I am not surprised he did not come your direction. He was not an inexperienced buck. Here is a call you may want to try. I suspect that many do not use this call the best way and end up doing the alarm bleat instead.
