SEDALIA, Mo. (January 19, 2020) – Sierra® Bullets and True VelocityTM introduce the first-ever competition-grade line of composite-cased ammunition. Capable of sub-MOA accuracy at extended ranges and single-digit standard deviation in muzzle velocity, this ammunition provides a level of performance and precision unsurpassed by brass-cased match-grade cartridges.
True Velocity has spent many years developing and perfecting reduced-weight, composite-cased ammunition for the US Military. This effort has resulted in a new, state-of-the-art manufacturing process capable of tolerances and in-process checks and measures unheard of even with the best brass cased ammunition available today.
Starting at the base, the True Velocity case features a precision formed primer pocket and burr-free flash hole in a steel alloy head, that offers increased strength and safety over conventional brass head case designs.
Inherent to the new manufacturing process, the composite neck and body of the True Velocity case offer exceptional wall thickness uniformity and results in precisely aligned features with minimal runout – results that handloaders try and achieve via fire forming and tedious outside neck turning operations when working with conventional brass cases.
Unlike brass case designs, True Velocity can control the internal geometry of the composite case independent of the external geometry and can fine tune the powder chamber to optimize the internal ballistics performance. Due to the efficiency of the burn, composite-cased ammunition typically requires 10% less propellant for the same muzzle velocity, which helps reduce barrel wear and heating, and reduces felt recoil and muzzle flash.
Sierra has over 70 years of experience producing the finest, most accurate, match bullets, where in addition to an extensive list of Q/C inspections, the accuracy capability of every lot of MatckKing® and Tipped MatchKing® bullets is verified in Sierra’s 300-meter underground test range prior to release.
Sierra® and True Velocity have selected the most uniform primers and propellants available for these new loads, and thoroughly tested these combinations in a broad range of conditions and rifles to ensure uniform, consistent performance.
When the True Velocity composite case is topped off with a precisely aligned and seated Sierra MatchKing or Tipped MatchKing bullet, modern adhesives are used to control the bond between the bullet and the neck, resulting in exceptional neck tension uniformity. Unlike brass cases, there are no mouth burrs, or excessive variation in neck thickness or annealing that will affect bullet release force in the composite-cased ammunition.
The end result is competition-grade ammunition with unparalleled accuracy and velocity uniformity, right out of the box!
Look for this new Sierra/True Velocity ammunition on store shelves in 2020 in .308 Winchester with Sierra’s 168- and 175-grain MatckKing and Tipped MatchKing bullets, and in 6.5mm Creedmoor with a 142-grain MatchKing bullet. Additional offerings will follow.
