Tournament Master® handgun bullets are built to satisfy the performance demands of serious competitors and recreational marksmen. The accuracy of these bullets, combined with unduplicated penetrating power, make them the bullet of choice for silhouette shooters and big game hunters worldwide. The traditional, flat base design of the Pro-Hunter® has been skillfully blended with Sierra's world-famous accuracy. Our custom-tapered Pro-Hunter® jacket design helps assure maximum expansion, optimum weight retention and deep penetration for game-stopping, one-shot performance. Sports Master® handgun bullets are engineered to provide consistent, reliable expansion over a wide range of velocities. Sierra has added a serrated "Power Jacket" on hollow cavity and hollow point bullets. On impact, the "Power Jacket" expands uniformly along the serration lines for consistent weight retention and maximum energy transfer.
