The 300 Blackout provides users a larger caliber option to 5.56mm in the same platform size. The 300 Blackout has an efficiency advantage compared to the 5.56 when used in shorter barreled firearms. While a 10.5” barrel is generally considered to be a “short” barrel for 5.56mm, many .300 Blackout weapons have barrels as short as 5.5” while still retaining effective ballistics. With the recent surge in popularity of this cartridge and the many platforms for it, new projectiles are being specially designed for this cartridge to ensure optimum feeding and best performance.
The 115 grain Dual Performance projectile from Black Hills is an example of one of the best possible choices. This new projectile, manufactured by Lehigh Defense for Black Hills, is monolithic copper, precision machined to provide ideal and effective performance from those shorter barrels. The frontal portion of the bullet is designed to easily expand to form an effective wound cavity. During this process the expanding petals then fracture, creating additional penetrating projectile fragments that pierce the stretched and stressed tissue, cutting their own separate wound tracks from the projectile’s remaining solid shank. The main shank of the projectile, once free of the petals continues on to ensure adequate penetration, even at varied velocities resulting from barrel lengths from 5.5” to the longer barrels of 16” or more. If you're using a 300 Blackout to defend your country, your city or your family, you need the best performance available. That performance comes from Black Hills Ammunition.
