I was on 15x zoom. My brother in law was back there yesterday with some folks he was showing around and he said he thinks it was possibly 100 yards. It was pretty hot at the time due to the other hunter being on our rear ends, so things were rushed. How ever far it was, it was still a great shot and dead on. Im thinking it was at least 100 yards because he said he put the 100 yard cross hair on its neck and let it fly lol.
