New Allegiance Ammunition Silent Strike Round

Allegiance_Ammo_Logo_large

Allegiance Ammunition manufactures ammunition meant specifically to fulfill high-performance needs. They describe a successful high-performance self-defense or hunting round as being able to “achieve adequate penetration to reach vital organs [and] expand or fragment when it strikes fluid filled tissue without exiting.” They offer a variety of lines including TechStrike, which is described as ideal for operations being carried out in sensitive areas where overpenetration or ricochet could be disastrous, and Silent Strike, described as being used for those in law enforcement. The latest round being offered in the Silent Strike line is a 9mm, and what makes it unique is its being both frangible and subsonic.

The new Silent Strike 9mm weighs in at 125 grain and has a lead-free Tungsten powder core. Allegiance Amunition lists its muzzle energy as 1050 feet per second and claims it is the only lead-free subsonic frangible on the market.

Frangible ammunition is gaining popularity in the industry and among the general shooting public as well. An increasing number of companies have begun producing frangible rounds in just the last couple years. There are a variety of uses for it from steel plate shooting to self-defense to hunting, so it’s great to see it being produced on a regular basis rather than only as an occasional specialty round. Do any of you shoot frangible ammunition?

From Allegiance Ammunition:

Most soft targets contain 85%-90% fluid. Allegiance uses a special blend of compressed powdered-metal to allow the bullet the ability to penetrate through thick hide, heavy clothing, and bone to get to the softer fluid filled tissue.
Once inside the target, the powdered-metal core begins fragmenting at an alarmingly fast rate, producing controlled penetration.
As the core expands into the soft fluid filled tissue, 100% of the bullets energy is transferred into the target. This is called High-Energy Transfer (H.E.T.). The expanding powdered particles pick up the surrounding damaged tissue and shove it forward, exponentially increasing the huge frontal shockwave of the bullet.
As the expanding powdered metal particles release the last amount of kinetic energy, they create thousands of wound channels. This creates so much hydrostatic shock that it  shuts down the central nervous system; stopping the threat instantly.

    Swirling Tungsten Nytrillium Death Cone!!! Whaaahahahahaha!!!

      Now with a hydrometer in every round for reliable expansion.

    So this is a lead-free Glaser Safety Slug?

    What if you are on your back getting kicked and the direct shot to the bad guy’s innards is up along his outer thigh? A supersonic hollowpoint or fmj might be able to travel the length of his upper leg and hit the arteries in his pelvis, but a frangible might more likely just crater his quadricep.

    • DanGoodShot

      Either way I’m pretty sure he’ll probably stop kicking you. It’s up to you what you carry.

    • Sunshine_Shooter

      A frangible would shred the arteries in that quadracep, and make that entire muscle group unusable against you for the duration of the fight. The vitals would be safe, but you would still be having a positive affect upon your assailant, possibly letting you gain a better position which would let you fire upon their internal organs and/or head.

    • Mattblum

      I have no idea about the effectiveness of this particular round. However, “cratering his quadriceps” will do enough damage to, if not kill the assailant outright, do damage that will not only incapacitate them, but likely prove fatal in the long run. That is why femur breaks are considered so dangerous. Serious damage to that area has a lot of potential to pull the bone into those arteries in the pelvis, which cuts them and causes the injured to bleed out rather quickly.

    FYI, Allegiance was formerly known as Extreme Shock ammo.

    • DanGoodShot

      I didn’t know that. Thank you. You would have thought that info would have been in the article.

    Snake oil

  • Anonymoose

    Do they still make those subsonic .223s?

  • Tyler Browne

    Damn, a muzzle energy of 1050fps?! So powerful they created a new hybrid system of measurement!

  • Copy Pasta

    It would have been if it weren’t another Katie A drive-by copy and paste.

  • AD

    How does the toxicity of tungsten compare to that of lead?
