I have used hand loaded 150g SST in my 300 WSM on Mule Deer and Antelope with great success. Jumped a mule deer at 40 yards and spine shot it. When I skined it, the hole was unreal. The entry hole was the size of my head. It didn't make the lower back straps look very good but the deer went down. I loaded 180g SST for my elk hunting trip in CO next month. Can't wait to see how they perform.
