Garland, Texas-based ammo maker True Velocity now offers its composite-cased .308 ammunition to the public. The cases consist of a steel base attached to a polymer case made in two pieces and joined together just below the shoulder. The new loads will be sold in boxes of 20 and loaded with 168-grain Nosler Custom Competition Hollow Point-Boat Tail bullets. The ammunition will sell for $69.99 a box.

Among the advantages, True Velocity touts its composite cases are 30 percent lighter than brass, and transfer much less heat to the chamber of the rifle due to the insulating properties of the polymer case. True Velocity also claims the internal dimensions of their cases allow for more efficient, consistent powder burn resulting in improved accuracy. They are non-reloadable, 100 percent recyclable, and can be picked up with a magnet by the steel base.

Founded in 2010, True Velocity makes its proprietary 6.8 TVCM cartridge as well as .50 BMG, .338 Norma, 7.62 Nato, .308 Win., 6.5 Creedmoor, and 5.56 Nato. The company is currently one of two ammunition finalists in the US Military’s Next Generation Squad Weapons (NGSW) Program that is testing replacements for the M4 carbine and M-249 Squad Automatic Weapon. True Velocity recently completed delivery of 625,000 rounds to the Army for testing in the NGSW Program.

The idea for composite ammunition has been around since the 1950s and has been tried in weapons systems like the Steyr ACR in the 1980s. With True Velocity now offering .308 ammunition to the civilian market, it may be that polymer ammunition’s time has finally arrived.
