I used a 160gr AB to harvest both an Elk and Moose this past fall out of my 7mm rem mag and it performed JFL. I never found any lead as in both animals the bullets produced pass thrus, good exit holes of 2 - 2 1/2", massive internal damage and dropped the animals within sight of the shot.

I loaded them just to try really but instantly fell in love with the accuracy, which provided a gain over my 160 NP Load. I will be loading them again next fall when I chase elk, so you could say I was impressed, pleased and confident in the AB on larger game. The NP is a proven bullet and no brainer choice if at all worried, the way I see either will work fine so let your rifle make the desicion based on which one shoots the best.
