CORBON's Traditional Jacketed Hollow Point ammunition made its reputation with high velocity loads. This high velocity, combined with their exclusively designed, jacketed hollow point bullets, makes for a very effective self-defensive/Hunting load. Penetration and expansion in test medium of 10% ballistic gelatin are excellent; expansion is consistently 2 times the original diameter of the bullet. Depending on caliber and bullet weight, penetration is between 9 and 18 inches. At CORBON, they believe that velocity is king! Higher energies enhance bullet performance and increase stopping power.
