Congrats on the elk. The 7mm 162 grain Amax appears to be better penetrator than the 208 grain Amax .308 bullet.
The second cow was initially shot at 463 meters with a 208AM fired from a .300WM. The cow was broadside and the wind gusted just a bit as the rifle fired, and the bullet hit her in the liver. It did not exit, and was not recovered.
It is good to know differences exist. It is like the difference between a 120 grain 7mm ballistic tip and the 140 grain ballistic tip. If I recall correctly, Scenarshooter reported something similar between the .308 155 scenar and a heavier scenar bullet in .308. My good friend has had similar success with Hornaday's standard 162 BTHP 7mm.
