Find 5.7x28mm Ammo At Best Price From Top Ammo Retailers

The FN 5.7×28mm designated as the 5.7 × 28 by the C.I.P. is a small-caliber, high-velocity, smokeless powder, rebated rim, bottlenecked, centerfire handgun and rifle cartridge designed and manufactured by FN Herstal in Belgium.

The 5.7x28mm is not a heavy-hitting round but is compact and accurate with light recoil.

5.7x28mm ammunition fires a relatively light 27-40 grain bullet at a high muzzle velocity of 1,600 to 2,200 feet per second. This caliber produces flat trajectories and can be used for both target shooting and hunting at close to medium range.
