History of FN 5.7x28mm Black Dragon Fang, V57 version:  Below is by the manufacturer" In this cartridge, the bullet is a 34 gr custom made solid copper alloy lathed projectile. It has patented drive-bands. It is composed of a proprietary copper alloy tempered to ensure hard-hitting penetration but also promote momentum transfer to soft tissues, organs, and bones. This round tends to crush bones and disrupt organs. This round does not just sail through tissue leaving a small hole. It is specifically engineered and designed for the 5.7x28 to achieve the highest accuracy with the bore/groove/twist specifications for this caliber. Independent testing conducted by Viper Weapons of Texas for government agencies shows our 5.7x28 rounds to be among the highest performing rounds available on the market."
