Both times was a very lite grunt with me trying to point the grunt call straight down. It's a Primos little BIG roar. I have also tried it out prior to being in the woods with it. I agree it might of been a little close to try. But like I said they were staring to walk away and I just was trying to grab there curosity, and it worked they bolted. I will try to attach the photo of the ten point in question, so I don't think it was a more of a mature buck.
