In rifles, this 100 grain #1560 Spitzer Boat Tail bullet with a heavy, double-tapered jacket ensures adequate penetration with reliable expansion on medium game. It is the boat tail counterpart to the flatbase #1540 Pro-Hunter bullet, but when ranges exceed 300 yards, the #1560 bullet is the choice for best downrange performance. This bullet is exceptionally accurate, and it may be used in 6mm cartridges, such as the 243 Winchester, 6mm Remington and magnums. It also is a very fine bullet for larger varmints at long ranges.
For handguns, the 100 grain #1560 Spitzer Boat Tail bullet is too “hard” for use in the field on game, because it will not expand adequately at the moderate velocities attainable from all cartridges except the largest wildcats. This bullet will perform to outstanding levels in long-range target or silhouette competition from barrels with standard twist rates.
For rifles in 30 caliber, these bullets are 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 165 grain #2145 bullet is best suited to medium game at all velocity levels, and game the size of elk could be taken with confidence providing velocity doesn't exceed 3000 fps and the range is limited to about 300 yards.
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.
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.
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.
