Throwback Thursday: Allegiance PowerStrike Frangible Ammo

By Dave Dolbee published on in Ammunition

When looking for a new home defense ammunition, well, could anything be more critical? I mean, your life is on the line, but so are the lives of your loved ones. You’ll need an ammunition that that will be absolutely devastating on the intruder, able to defeat light barriers such as glass, wood, and heavy clothing, but not over penetrate so much that you have to worry about going through multiple layers of drywall and risk injuring or killing an innocent loved one. The solution is the best self-defense round you may never heard of—Allegiance Ammunition PowerStrike.

The PowerStrike and the SAR 9mm proved to be a good combination.

PowerStrike is second to none when it comes to self-defense ammo. PowerStrike is also ideal for range time or competition. On the range, you can afford to shoot PowerStrike. In fact, it will be in line with many practice ammunitions. For competition, nothing is safer than a frangible round on steel.

Not long ago, I had the opportunity to spend a day at the range with Allegiance Ammunition CEO Jeff Mullins. During testing, I witnessed Mullins unloading magazine after magazine full of ammo on a steel target no more than three feet from the muzzle without fear of a ricochet! How’s that for safety on the range?

The secret to PowerStrike is its High Energy Transfer (H.E.T.) technology. PowerStrike is a lead-free powder metal High Energy Transfer (H.E.T.) round designed to create controlled penetrating fragmentation in soft targets. It is excellent for hunting small, large and dangerous game as it can penetrate thick bone and hide. For tactical applications, it can penetrate light barriers to reach the target while still fragmenting inside the target. High Energy Transfer means no exit from soft tissue. PowerStrike delivers total energy transfer inside the target, which means one-shot stops. PowerStrike will not ricochet, but disintegrates back to powder metal dust on surfaces that cause a lead FMJ HP bullet to ricochet.

The secret is in the construction. The bullet holds tight in solid materials such as wood or bone to retain its shape and penetration power, but disintegrates in softer fluid-filled mediums such as tissue. In fact, try PowerStrike on a game animal. The first thing you will notice is the devastating effect of the energy transfer. After recovering the animal, you’ll notice how the bullet breaks into lethal, minute particles creating a wider wound cavity that results in severe shock trauma to the soft target.

How it Works

A successful tactical, self-defense and hunting bullet must be able to do the following:

  • Penetrate light barriers to reach vital organs.
  • Expand or fragment when it strikes fluid filled tissue without exiting.

Typically, most soft targets contain 85%-90% fluid. Allegiance bullets use a compressed, powdered-metal core giving them the ability to penetrate thick hide, heavy clothing and bone.

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 tissue, 100% of the bullet’s 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 shock wave 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; it instantly shuts down the central nervous system.

    I purchased this ammo from Cheaperthandirt when it was on sale. I had continuous feed problems with multiple mags for both my Springfield XDM .40 and my Shield .40. I would not recommend his ammo based on my experience.
