I never had any luck with them until this year. I called in a 8 and a 9pt that were about a 100yds past me. They both were on the same trail about a 1 1/2hr apart. They both turned around and came right in. The 8 was 15 yds broadside, I let go, and the 9 was 30 yds behind me( no shot). I used the grunt because I had nothing to lose, both bucks were heading away and I wouldn't see them again that day.
