HRNDY BLK 5.7X28MM 40GR V-MAX 25/250

Description

Hornady Black in 5.7x28mm is a practical choice for shooters running pistols or carbines chambered for the cartridge who want a round built around a precision varmint bullet rather than a full-metal-jacket training load. The 40-grain V-MAX is a polymer-tipped projectile: the tip initiates expansion on impact, and the jacket is engineered to fragment consistently rather than simply deform. That construction is what separates it from ball ammunition at similar velocities — the energy transfer happens rapidly and predictably rather than passing through with minimal disruption.

Hornady loads this with a brass case and Boxer primer, which matters if you reload. Boxer-primed brass is decapped and reprimed with standard tools, so the cases can go through a reloading cycle rather than being treated as disposable. For 5.7x28mm, where brass can be harder to source than for common pistol calibers, that is a practical advantage.

The Black line is Hornady’s designation for ammunition optimized for modern semi-automatic platforms, and this load reflects that focus. The propellant charge is selected to function reliably in the gas-operated actions common to 5.7x28mm firearms rather than to meet a specific pressure floor with margin to spare. Muzzle velocity from a standard test barrel runs at 1,810 feet per second, producing 291 foot-pounds of energy — figures that sit comfortably within what the cartridge was designed to deliver. Available in 25-round boxes or by the case of 250 rounds.
