True Velocity Ammunition Inc, the company known for selling .308 Win. rifle cartridges loaded with composite casing technology, is now expanding its ammunition product line to also offer 5.56 NATO composite cartridges. True Velocity’s composite casings are intended to make rifle ammunition be more lightweight, accurate, consistent and reduce the amount of heat transfer from the ignition of propellants to the chamber area of a firearm. The new 5.56mm cartridges will be loaded with projectiles weighing 55, 69 and 77 grains, three very popular bullet weights for this caliber. By loading both the .308 Win. and 5.56 NATO rounds, the company now covers two of the most popular and versatile rifle cartridges used in North America for hunting, sport, recreation, self defense and tactical uses.

“There are hundreds of millions of rounds of 5.56 ammo consumed in this country every year,” said True Velocity Chairman and Co-CEO Kevin Boscamp. “We’re extremely excited to make True Velocity’s composite case technology available to the shooters who rely on this caliber. I’m confident they will see very quickly what makes our ammunition superior.”

True Velocity’s new 5.56 NTAO product line will be the company’s first to be loaded using their Generation 3 advanced loading techniques which reflects a higher level of control, precision and innovation in the commercial ammunition industry.

  • Projectile: 55-grain Full Metal Jacket (FMJ)
  • G1 Ballistic Coefficient: 0.243
  • Muzzle Velocity: 3,170 fps
