For missions requiring quiet performance, look to the quiet professionals at Black Hills Ammunition, and the 300 Blackout 198 grain Dual Performance round. With precision machining of solid copper it is possible to design and produce projectiles accomplish things not possible with conventional lead core projectiles. This is accomplished through the magic of CNC machined monolithic projectiles made by Lehigh Defense for Black Hills.
This is an optimum balance of on-target effectiveness and penetration. The shank of the projectile then continues on to penetrate to around 20” as demonstrated in 10% ballistic gelatin. This load not only expands to provide good terminal performance, after expansion, the three expanded petals separate from the shank of the projectile to cut three separate wound tracks, further increasing terminal effectiveness. Enter the 198 grain Subsonic Dual Performance round. Most bullets, especially rifle bullets do not expand well, or at all, at that velocity.īlack Hills Ammunition now offers a very good solution to that problem. One of the challenges of choosing the quieter subsonic version is getting effective on target performance with a velocity of around 1000 fps. Originally designed by JD Jones of SSK and called the 300 Whisper, this unique cartridge now generally called the 300 Blackout allows one weapon the option to fire a supersonic cartridge with power approximately equal to the Russian 7.62x39, or with a change of a magazine, to fire subsonic ammunition, that with the use of a suppressor, makes the cartridge, if not silent, much quieter, and likely to be noticed or recognized as a gunshot. Warning-icon WARNING: This product can expose you to Lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm.The 300 Blackout.

Suppressor Safe - The projectile is machined from solid bar stock. In an extreme high stress situation, where shot placement is likely not going to be perfect, this technology provides multiple wound channels coupled with a large energy transfer and a deep penetrating base, meeting all of the requirements for stopping a threat instantly. In personal defense applications, Controlled Fracturing technology is the most effective way to neutralize a threat. Unlike traditional expanding bullets which mushroom and dramatically limit the bullet’s penetration and provide only one wound path, Lehigh’s Controlled Fracturing ammunition creates an initial energy transfer, multiple wound paths, and a deep penetrating base – a far more effective bullet. The bullet shank, now back to bore diameter, continues penetrating straight and deep along the initial impact path. Controlled Fracturing bullets are produced from either solid copper or solid brass and are pre-stressed at specific points so that after a predetermined penetration depth, the razor-edge petals deploy, releasing an energy spike and then separate and radiate outward from the primary path of the bullet. These bullets are designed to deliver maximum terminal performance.
Lehigh originated Controlled Fracturing Technology.
