Lehigh Defense Introduced Close Quarters Fragmenting Bullet

    Lehigh Defense has introduced their new Close Quarters Bullets. In short, its a reverse RIP, designed for maximum penetration. Machined from solid bar stock, the round is a combination of an aluminum core and a pre-stressed jacket. When the round hits, the core will push back on the jacket to then fragment and launch the petals in their own unique directions.

    Lehigh is starting the line with a 78 grain .308 round which is now available for purchase in a 300 BLK loading and as a separate round for loaders and reloaders.

    Bullet Specs:

    • Caliber: 308
    • Bullet Weight (gr): 78
    • Length (in): 220
    • BC (G1): 249
    • Minimum Twist Rate: 1:10
    • Velocity (fps): 2,350-4,200
    • Box Qty: 50

    Lehigh Defense Announces Close Quarters (CQ) Projectiles & Ammunition

    Lehigh Defense announces the addition of a seventh technology (CQ) to our growing list of Projectile Technologies.

    Yes, E=MCSq and it is a beautiful thing. Double the bullet weight and the energy doubles. Double the velocity and the energy quadruples. How can you beat that? We design the world’s most innovative projectiles, that is what we do and the center of this passion is science, not voodoo, science. Lehigh has harnessed old Al’s work on energy equivalency and channeled it to a new bullet technology; we are calling Close Quarters (CQ). This technology utilizes hyper velocity to effectively transfer enormous energy to the target based on mass-energy equivalence. Lightweight, high energy projectiles using powdered metal and plastic binders have been done before. Instead of fragmenting the bullet to dust upon impact, Lehigh has designed specific densities for the fractured petals providing applicable penetration and an effective energy transfer.

    The CQ is a lightweight, hyper velocity design using an aluminum core and pre-stressed jacket. The aluminum core initiates the expansion slightly after contact, pressing back into the pre-stressed jacket and activating a violent, incapacitating energy transfer. The aluminum nose optimizes feeding and provides a barrier blind entry. The pre-stressed jacket separates into petals sized for appropriate penetration based on the specific cartridge. These petals, base, and core are all designed to penetrate no more than 18″, transferring a huge amount of energy to the target in a very short timeframe.

    First CQ Product to be Released

    The 300 AAC Blackout / Whisper* 78gr High Velocity (2,800 fps) Projectiles and Ammunition. This will make Lehigh the only company that can offer a complete line of 300 AAC Blackout / Whisper* Projectiles and Ammunition (From Subsonic to Hypervelocity).

    * Whisper is a Trade Mark of SSK Industries
