SAS, I used to have a 140AB pulled from a bull elk. That bullet crushed both shoulders of my largest bull elk, and was under the hide on the far side. That was outta my 270WSM. Very good bullet too. I am not sure Nosler puts out a bad .277" bullet. I lost the bullet in between PCS moves but man, it was just like the bullets that come out of the jugs. That was shot into the elk at about 150/175 yards. Put him down right there though, after a botched 1st shot.
