For the last ten years plus all i have used is hornady 7mmm08 139 sst and the old box of 139 gmx. All my meat animals i try to neck or head shots and had no real issue. Stags from now on get the puffy neck so have to be careful with that but most stags i shoot are behind the shoulder. Never had a issue with the sst it self, you have to play your part. Never shot past the 450y with them.
