I have used the 180gr .308 in my .30-06 to take Elk, black bear, white-tail and Mule deer at ranges from 75 yards to 200 yards and they have always performed well for me. I recovered the bullet from the elk, but none of the others and it looked like the photos in the magazines, other than the blood and hair, a perfect mushroom. I've been using them for a long time and until they let me down, I'll continue to use them. I have them for my 6.5X55 but haven't had the opportunity to use them yet.
