I don't know. I will never shoot enough elk to determine that. But I have killed elk with 165 Speer hot core from a 30-06 and 225g TTSX in .338 Win Mag. I hit the first better with the 165 Speer and broke both shoulders. The elk made it 50 yards down hill because it was rolling. However, I had a cousin who guided and hunting in the Bob Marshall for 40 years. He much preferred partitions and later Swift A Frames for elk.
