Might also add that every Barnes X recovered without any petals still has a far wider, flat front than "caliber sized" This also applies to other petal-type bullets, including the discontinued Fail Safe.
As an example, I put a 120-grain "original" X-Bullet started at 3000 fps into the near shoulder of a BIG axis deer as it quarter toward me at around 125 yards. The buck ran 30-some yards and keeled over. Found the bullet under the hide at the rear of the opposite ribs. It retained 93% of its weight, and the front end measured .41 inch in diameter.
