FEDERAL 300 WSM 180GR HI-SHOK SP (25 Round Bag)

Massammo.com is proud to offer a cartridge that until recently was reserved for government and law enforcement use only but can now be purchased with over-runs of the product to the commercial market.

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 complexed 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.

HELO Defense/Hunting 55 grain .223 has shown to be an ideal cartridge for hunters of medium sized game. Our cartridge has been proven to be the most effective defense/duty round on the market for many reasons:
