The NPA proprietary HELO family of products was originally designed for law enforcement application and specifically engineered to performance specifications requested by law enforcement with complex tactical needs. Unlike bonded jacketed bullets, the HELO is formed from a solid piece of high-grade virgin copper. After a proprietary cavity is formed, the copper bullet is subjected to a complex proprietary manufacturing process which allows the projectile to achieve maximum penetration and expansion while retaining 100% of its weight through certified ballistic gel. The HELO does not break apart like many other copper hollow point bullets seen on the market, giving it a significant advantage in strength and integrity.

Please note that the bullet of the NPA HELO Defense 9mm solid copper hollow point has been treated and sealed with black oxide that acts as a lubricant and barrier which reduces drag and prevents copper fouling in a firearms barrel. Very few bullets are coated with black oxide because it is expensive, time consuming, and difficult to properly accomplish. The black oxide coating can be rubbed off if someone attempts to polish the bullets with a polishing compound and rag or with a dry rag repeatedly rubbing the bullet. Do not attempt to polish or remove the black oxide coating, it is there to improve the product. NPA Engineering Team.
