Here's a 300 gr Hornady SST-ML I recovered from last years deer. The deer was approximately 135 yds. and was shot uphill. The bullet struck the shoulder, then the spine, and finally came to rest just inside the hide on the far side. I'm not sure about the weight retention, but I was shooting 90 gr. vol. of BH209 out of a Traditions Pursuit. Due to striking the spine, the deer dropped in his tracks.
And here's the buck, shot on Christmas Day.
