What is SinterFire 5.56x45mm NATO Ammunition?

SinterFire 5.56x45mm NATO is a frangible training cartridge designed to replicate the ballistic characteristics of standard military 5.56 NATO rounds, while minimizing ricochet and over-penetration risks. Unlike traditional lead-core ammunition, SinterFire uses a compressed copper-tin composite projectile that disintegrates into harmless particles upon impact with hard surfaces.

This makes it an ideal solution for indoor ranges, steel target shooting, and tactical training environments where safety and environmental responsibility are critical.


How It Works

The unique frangible bullet design is created using powder metallurgy technology. By compressing powdered copper and tin at high pressure, SinterFire forms a dense, accurate projectile without the use of toxic lead. Upon impact with steel or other hard barriers, the bullet breaks down into dust-like particles, drastically reducing the risk of ricochet injuries.

Despite its frangible nature, the ammunition maintains reliable accuracy, muzzle velocity, and point-of-impact consistency — closely mimicking standard duty rounds for effective training transfer.


Benefits of SinterFire 5.56x45mm NATO Ammunition

  • Lead-Free & Eco-Friendly – No hazardous heavy metals, safe for indoor ranges and environmentally conscious shooters.

  • Reduced Ricochet Risk – Projectiles disintegrate on hard surfaces, enhancing shooter safety.

  • Reliable Accuracy – Matches the performance of duty ammunition for consistent training outcomes.
