The Sierra 150 grain #2130 bullet features the brand's unique double-tapered hunting jacket, a design that has been proven reliable in the field under a wide range of conditions. This bullet is specifically optimized for medium game, offering exceptional accuracy that gives hunters a distinct advantage. The #2130 is renowned for its reliable expansion and deep penetration, coupled with Sierra's classic Spitzer flat base profile. These qualities make it a top choice among 30 caliber riflemen seeking a bullet that delivers consistent performance in the field. While the Sierra Pro-Hunter design is typically considered too "hard" for most handgun calibers, it shines when used in more powerful 30 caliber handguns, such as those chambered for the .308 Winchester or similar-sized cartridges. For these handguns, the Pro-Hunter bullets can be used effectively with maximum hunting loads at short ranges. The flat base design of the #2130 is also ideal for cartridges with limited powder capacity and short necks, as it intrudes less into the powder space compared to a boat tail, making it an excellent choice for those specific cartridge types.
