The 85 hpbt has a thicker jacket than most traditional hollow points, giving it better penetration. My boy shot a big 5 year old mule deer buck with one at 410 yds one time. It made a good mess of his lungs, and the rear part of the jacket was just under the off side hide. Buck went about 50yds a d piled up. I shot a big wolf with one at about 350yds, and had an exit through the ribs that was about the size of a 50 cent piece. Killed lots and lots of deer with them without any fanfare. These bullets are extremely accurate as well.
