Varminter bullets are made to meet the extreme demands that varmint hunting places on bullet performance. Exceptionally accurate on small targets, lightly constructed to provide explosive expansion while minimizing ricochets, and lightweight to obtain high velocities with flat trajectories, Sierra Varminter is the standard against which other brands are measured.
Spitzer - In rifles, this bullet is fully capable of producing 1/4 minute of angle accuracy at velocities that would destroy most other bullets. The bullet has the Spitzer point shape and a flat base. This bullet style is the choice of many accomplished varmint hunters. It features precisely drawn jackets to assure pinpoint accuracy and reliable expansion, even at maximum ranges. This bullet is slightly "hard" at 222 or 223 Remington velocities, but are especially well suited for velocities from 22-250 and 220 Swift cartridges.
SMP - Semi-Point - In rifles, the Semi-Point design allows this style of bullet to expand faster than a Spitzer style due to a generous amount of exposed lead at the tip and the slightly larger opening in the jacket. Capable of outstanding accuracy, this bullet can be an excellent choice for varmints and small game in many early 22 centerfire rifles, which have slower twist rates than those commonly used today. The Semi-Point shape reduces bullet length for a given weight, making the bullet easier to stabilize. The penalty is that a Semi-Pointed bullet has a lower ballistic coefficient than a Spitzer-pointed bullet of the same weight. This bullet can also be used in modern rifles with faster twist rates.
RN - Round Nose / Hornet - For rifles, this bullet is formed with a thin-walled jacket and soft core in the traditional roundnose shape for cartridges such as the 22 Hornet, 22 K-Hornet, or 218 Bee at muzzle velocities in the 2600 to 2900 fps range. The thin jacket and rounded nose of this bullet provides outstanding accuracy and effective expansion on small varmints at these modest velocities. This bullet is ideal for barrels with 1x16" twist rates and muzzle velocities that require a "short" bullet for proper stability. It is also effective in rifles firing medium-capacity cartridges, such as the 222 Remington and 223 Remington, for target and varmint shooting at muzzle velocities up to 3500 fps.
HP - Hollow Point - For rifles, this high-velocity bullet is designed to give precision accuracy with the explosive expansion of Sierra's Varminter-style construction. Although the bullet may prove to be somewhat "hard" at Hornet velocities, it can be extraordinarily accurate at these lower velocity levels.
