Sierra Sports Master 9mm Caliber 115 Grain JHP Rifle Bullets

In reloading Sierra Sports Master Bullets are constructed to meet military specifications for impact toughness. The jackets are formed to specific velocities and pressures to produce optimum uniform expansion. Sierra has incorporated a patented process which, during the manufacturing, actually seats the bullets in the bore throats. The necks of these slugs are precision machined from solid copper bar stock. The tips are swaged flat and the hollow points are tapered. Upon impact the serrations within the hollow points expand and trap the gasses from the central vacuum. The result is greater energy retention and greater weight retention with less fragmentation risk. Sierra’s mechanical design is also patented or approved by the SAAMI JSA.
