FN Herstal 5.7×28 Ammo – 50 Rounds of 40 Grain V-MAX Ammunition

In 1991, FN Herstal introduced the 5.7x28mm cartridge for use in their P90 PDW. 5.7x28mm ammo is very compact – allowing for improved magazine capacity as well as a light bullet with high velocity. These features make it an effective round against most body armor.
