I've also witnessed one where the mounting screw would come lose under recoil. I was helping a friend sight one in at the range a couple years back and after a few rounds the scope would loosen repeatedly. This was on a 300 win mag. I can't speak for the Swarovski one as it's mounting system might be different but after first hand experience with the Burris I wouldn't use one.
Since the majority of hunting shots are at short range with no compensation needed I find the extra weight, low to average optical clarity and the risk of losing zero not worth it. I prefer a good range finder and a tried and tested turret style scope for the longer shot's.
