NPA HELO Defense / Hunting 62 grain 223 

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.
