For me I've only had 1 Buck respond to rattling so I don't do it much. The grunt call I have had success with. My biggest to date came on line to the grunt. I mostly grunt when I see a buck moving away from me. If I have had a lot of rut activity in the area I will blind call every so often. This time of year I use Buck urin. I will break out the doe urin the last weekend of October.
