Yep. Was hunting gemsbok in SA. Very thick bush. A lot of sneaking around and the sun was getting low with us looking straight into it, so there was considerable glare. We finally set up for a small opening in the bushes. The PH told me he would let me know which animal to shoot as they were passing single file through this small opening. I was concentrating on getting a quick shot and relied on what the PH said. Finally a gemsbok walked through and the PH said to shoot. I made a good shot and the gemsbok only went about 50 yards. We walked up to it and saw one horn was short, bent, and splintered in about 5 pieces. Since it was less than 24 inches, the outfitter did not charge me and I was able to shoot another one. What irritated me was the PH said he knew the gemsbok had a damaged horn but told me to shoot anyway. I was like... What?? Yes it is my responsibility to pull the trigger or not but under the conditons, I was concentrating on the exact area of the gemsbok to aim at and I did not notice the damaged horn. I thought the PH should have at least warned me or told me to hold the shot.
