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.
For rifles, this 55 grain #1355 Full Metal Jacket Boat Tail bullet was designed specifically to duplicate the military M193 bullet, and it is intended for use in semi-automatic rifles, such as the AR-15, M16 and Ruger Mini 14. It features an exceptionally heavy full metal jacket with a cannelure properly located for crimping and positive feeding. This is an excellent bullet for hunting varmints and small game where pelts are to be preserved. It should be loaded to medium velocities for this purpose.
In handguns of 22 caliber, this is a non-expanding bullet that will minimize damage to pelts as well as meat in small game. It is best used at medium handgun velocities to prevent tumbling upon impact. It is an ideal choice for the trapper or pelt hunter with a handgun in a 22 centerfire caliber.
The #1355 was introduced in 1985.
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 in 30 caliber, this 165 grain #2140 Hollow Point Boat Tail bullet, which is patterned after the world-famous 168 grain MatchKing bullet, was designed for shooters who desire a hunting version of that famous MatchKing. It is slightly "harder" than its 165 grain Spitzer Boat Tail counterpart and will give superior penetration and good expansion on medium game with excellent accuracy. This is a good medium-weight bullet choice for shooters of 30 caliber magnum rifles who desire a bullet that will not deform at the point.
For handguns chambering 30 caliber cartridges, this 165 grain #2140 bullet is "hard" and will expand in medium to large game only when driven at a muzzle velocity of 2500 fps or more, which is achievable in the 308 Winchester cartridge in the Remington XP-100 handgun or a similar combination. It can, of course, be used for handgun silhouettes or other target purposes.
