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.
In handguns, because of the velocity constraints caused by short barrels, the primary usefulness of a semi-point bullet design is in cases where the twist rate may not be adequate to produce the best accuracy with a spitzer bullet. The relative shortness of the semi-point design can improve bullet stabilization and accuracy. This bullet will not give explosive expansion at longer ranges, but due to the wide jacket opening and generous exposed lead tip can be useful at shorter ranges for fur bearers whose pelts are to be preserved.
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.
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.
Designed for hunting, specifically for large bears, and for Handgun Metallic Silhouette competition with magnum calibers, this 300 grain #8830 Jacketed Soft Point bullet was introduced in 2004. Its construction ensures deep penetration on the largest game due to a heavy jacket and extremely hard 6% / 4% core. This is the heaviest bullet Sierra produces in the 45cal pistol lineup and should be used in a 45 Colt if penetration is a must, and it can work in the 454 Casull or similar cartridges easily. It has an established reputation in the game fields of North America and is considered to be the bullet for hunting dangerous game with a handgun. It is not, however, recommended for deer-size game because of its hardness. Because this bullet has a cannelure and can be roll-crimped, it may be loaded in cartridges and used in modern rifles with tubular magazines.
When seated to the cannelure, this bullet can have an overall length that may not feed well in some lever action rifles with a shorter carrier. Recommended OAL of 1.650” in the 45 Colt and 1.755” in the 454 Casull.
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.
