I only killed one white tail this year. 62gr Dual Performance. It took the front 1/3 of the heart and disappeared it. However, due to the angle (broadside) and the impact (low in the chest, aiming for the heart), there wasn't much deer that it "passed through".

The damage to the heart was impressive, and upon the inside of the ribcage on the exit side, I noted about a 1.5-2" diameter area of dispersion for the fragments of the front of the projectile. The exit was, again, not really note worthy. Entrance and exit of the ribcage proper shows much more trauma from 70gr TSX. However, the damage to the heart was indeed in keeping with a fragmenting round. I will probably standardize on 70gr TSX, after now having used:
