CH/John: Yes that is a 160 gr 7mm BBC that hit a bull elk from above and behind, over the withers into the back of the neck just forward of the shoulders; traveled the full length of the neck busting up a lot of vertebrae and pulped a lot of muscle. I found it under his chin while caping.
Weighs about 159 gr,and is expanded to about 70 caliber as you see it.
