National Police Ammunition American Made


The HELO SR projectile is unlike any other duty cartridge currently on the market today, the latest trend in ammunition is expensive milled projectiles that fragment upon impact failing to penetrate to minimum FBI Protocol depths, unable to defeat barriers, and limited retained weight required by the FBI Test Protocols.  

The NPA Patented Pending HELO SR is designed for law enforcement and specifically to pass and exceed all FBI performance protocols.

Traditional ammunition utilizes a polymer tip at the nose of the projectile to assist in accuracy and energy transfer at the point of impact, unfortunately polymer / plastic deforms and melts in flight,  does not retain its shape, and lacks density when it impacts its target.

NPA patent pending SR ballistic insert utilizes a sintered tip that will not deform in flight and acts as a barrier blind round by allowing the ballistic tip to defeat intermediate barriers then release from the main body of the projectile once encountering soft tissue allowing complete energy transfer and controlled expansion of the main body of the hollow point bullet mitigating risk of over-penetration
