For rifles in 30 caliber, this bullet was designed for medium- to long-range hunting with cartridges having medium to large case capacities for powder. These bullets often display match grade accuracy from accurate hunting rifles. The famous Sierra Spitzer Boat Tail shape assures flat trajectory, excellent resistance to crosswinds and vertical winds, and maximum energy delivery to the target. Good penetration and expansion are characteristic of these bullets even at the reduced impact velocities at long range. With the weight range available, at least one of these bullets will prove ideal for almost any 30 caliber cartridge. The 150 grain #2125 bullet is best suited to medium game at all velocity levels.
In handguns chambering 30 caliber cartridges, prior to the introduction of the Remington Model XP-100 (and similar handgun designs) utilizing larger rifle cartridges, the usefulness of these bullets was limited. Now, these bullets have a very definite niche as superbly accurate hunting bullets. Previously considered “too hard” for expansion, they perform well at the 2500 fps muzzle velocities achievable in the 308 Winchester and larger cartridges. Ease of loading and precise concentricity contributes to their excellent accuracy. Sierra’s Spitzer Boat Tail design assures flat trajectory and high energy delivery downrange with low sensitivity to crosswinds and vertical winds. These bullets are suitable for varmints through large game at all ranges a prudent handgunner would normally attempt.
In rifles chambering 22 caliber cartridges of moderate to large powder capacity, this famous bullet is perhaps the most efficient 22 caliber bullet available for varmints at long range or targets. The spitzer boat tail design provides exceptional accuracy and a flat trajectory. The high ballistic coefficient of this bullet provides less sensitivity to crosswinds and vertical winds and greater retained velocity and energy downrange. It is an excellent choice for most 22 centerfire cartridges but is at its best in the 22-250, 220 Swift, and similar high-velocity cartridges. For target shooting purposes this 55 grain spitzer boat tail has been surpassed by the heavier MatchKing bullets in 22 caliber, but in many rifles it delivers match-grade accuracy.
For handguns, because it has the Sierra high velocity construction, this bullet is too "hard" to be recommended for hunting applications. However, it features the famous Sierra accuracy and is certainly an excellent choice for long-range accuracy under all conditions. If a boat tail bullet with extremely high accuracy fits your needs for target shooting, then this bullet should be your choice.
The #1365 was introduced in 1980.
In rifles, this 100 grain Spitzer bullet #1540 has a heavy, double-tapered jacket to ensure adequate penetration with reliable expansion on medium game. This bullet may be the correct choice for hunting large varmints as well as deer or antelope. It also may be the bullet of choice in some rifle's because its flat base construction enhances accuracy in that particular rifle.
In handguns, the 100 grain #1540 Spitzer bullet is too "hard" for use on field game due to the moderate velocities from all but the largest wildcat cartridges. However, this bullet will deliver to outstanding accuracy in long-range target competition and high momentum downrange for silhouette competition from handgun barrels with standard twist rates.
The #1540 was introduced in 1956.
For rifles, this bullet is designed specifically for the 375 Winchester cartridge. It has Sierra's unique PowerJacket and provides outstanding terminal performance. Sierra's Power Jacket ensures positive but even expansion in conjunction with good penetration on medium to heavy game. The cannelure location is correct for crimping, and the flat point was designed for use in tubular magazines. This bullet is also very effective in the 375 H&H Magnum, but velocity should be kept around 2200 fps to avoid over-expansion in game.
For handguns, although the bullet is designed for rifles chambered for the 375 Winchester cartridge, it quickly found a home in the 375 Super Magnum revolver. Thompson Center currently chambers the T/C Contender for the 375 Winchester as well. Designed for the modest velocities generated by 375 Winchester rifles, this bullet performs very well in a handgun. The large amount of exposed lead at the tip and the PowerJacket skiving assure quick, even expansion at all suggested velocities and ranges, making this bullet the best choice in this caliber for field use on game. Traditional Sierra accuracy assures success on medium to large game and silhouettes.
The #2900 was introduced in 1987.
The 150 grain #2130 has the Sierra's unique double-tapered hunting jacket that has been field proven under all conceivable conditions. The 150 grain #2130 bullet is best suited to medium game. This bullet is extremely accurate, providing an undeniable edge in the game fields. Reliable expansion and deep penetration blended with Sierra's classic Spitzer flatbase profile makes these the bullets of choice with many 30 caliber riflemen.
For handguns, Sierra's Pro-Hunter design is generally considered too "hard" for all but the most powerful of the 30 caliber handgun cartridges. Handguns chambered for the 308 Winchester cartridge or cartridges of similar size can use these bullets over maximum hunting loads at short range. Due to their flat base design, Pro-Hunter bullets are an excellent choice for a cartridge with limited powder capacity and a short neck, because these bullets intrude into the powder space less than a boat tail.
