I shot one deer that was facing me and hit it in the middle of the neck and recovered the 120 tsx under the hide on the hind quarter. So, it took out the spine in the neck, traveled the full length of the deer and completely penetrated the hind quarter, broke the leg bone and stopped under the hide. Hows that for penetration? Wouldn't hesitate to use an accubond either. I have yet to recover one on 6 deer kills. All pass throughs.
