Bullet 101
There is no “universal” bullet – that is, no single bullet for all shooting applications and all shooting conditions. The information below has been prepared to help you choose the right Sierra Bullet for you in any application, whether hunting or target shooting. Bullet selection is, of course, a personal preference, but there are some important technical considerations that must be addressed. We hope that the rifle bullet descriptions in this section will help you make the correct bullet selections for your applications as well as your shooting conditions.

RIFLE BULLETS

The rifle bullets in Sierra’s product line are arranged in six classifications, depending on the intended application, design features, and the range of cartridges that may use the bullet. Two of these classifications include all of Sierra’s match target bullets for target shooting, and the other five classifications are for hunting applications.
These seven classifications are:




Varminter Bullets:
This classification of bullets is designed specifically for rapid expansion and instant kills on larger varmints and small game. The shapes of bullets in this classification include hollow point (HP), spitzer pointed flat base (SPT), and semi-pointed (SMP). Bullets in this classification have thin jackets to enhance expansion but with sufficient strength to be fired at the highest muzzle velocities in the cartridges for which they are intended. Bullets labeled as Blitz are designed for medium velocity (under 3600 fps).
Hornet Bullets:
These are 22 caliber bullets within the Varminter family. These bullets are of 40 and 45 grains in weight designed in the traditional shape for the 22 Hornet cartridge. Their purpose is hunting varmints and small game, and they are designed to expand reliably at velocities in the 2500 to 2800 fps range, although they can be loaded in cartridges generating up to 3500 fps muzzle velocity.



BULLET DESIGNS
Sierra also uses several basic shape designs for rifle bullets, although some features of different shapes may be incorporated into a single bullet. Shape and characteristic features easily distinguish each design. The most popular are described below.









HANDGUN BULLETS

Sierra’s handgun bullets are separated into three classifications, depending on the intended application, design features, and the range of cartridges that may use the bullet.
These three classifications are:
SportsMaster Bullets: Handgun bullets designed for hunting or personal defense, built for reliable expansion. SportsMaster bullets intended for use in revolvers and rifles with tubular magazines have a cannelure to facilitate roll crimping. The bullets in this classification are available in three different configurations; Jacketed Soft Point (JSP), Jacketed Hollow Point (JHP), and Jacketed Hollow Cavity (JHC) styles.
TournamentMaster Bullets: Competition-style handgun bullets built for accuracy. TournamentMaster bullets are designed and manufactured for exceptional accuracy and are non-expanding at typical handgun velocities. With no cannelure, they are designed for taper crimping. TournamentMaster bullets are available in two design configurations: Full Profile Jacket (FPJ) and Full Metal Jacket (FMJ). They are excellent selections for any type of hand-gun target competition.
Sig V-Crown Bullets: Personal defense bullets built for optimal weight retention and expansion.
BULLET DESIGNS
Jacketed Soft Point (JSP) is a classic bullet design for deep penetration with high weight retention on medium and large game. Features include a special lead alloy core formulated to provide proper expansion qualities. On impact, the bullet will allow the core to flow over the leading edge of the jacket, in effect locking the core in place and retaining as much mass as possible. The jacket consists of specially dimensioned walls formed by Sierra’s unique progressive draw process, which results in uniformly tapered, concentric walls with a heavy base. The JSP design is used in Sports Master bullets.
Jacketed Hollow Cavity (JHC) is a design unique to Sierra and acclaimed for superior performance. Positive but controlled expansion is ensured by the unique cavity, which is formed in the core prior to final nose forming. The result is a small opening in the bullet tip over a large cavity for a good ballistic coefficient and balance. Sierra’s Power Jacket provides positive, uniform and controlled expansion by means of specially placed skives in the jacket around the tip of the bullet. The JHC bullet design is used generally for handgun bullets in several calibers.
Jacketed Hollow Point (JHP) is an old standby Sierra bullet design featuring Sierra’s unique Power Jacket. The skived, tapered Power Jacket is engineered for positive but even upset, while the core is specially formulated to provide maximum expansion over a wide velocity range. The large opening and Power Jacket skiving assure unfailing expansion under all conditions and strike angles. The bullet profile is engineered to guarantee smooth, trouble-free feeding in semi-auto pistols and is complemented by the jacket that covers all but the point of the bullet. These features combine to form a bullet that will function flawlessly from all auto-loading handguns with excellent terminal ballistic performance. A fast-expanding design for low to moderate velocities and self-loading handguns.
Full Profile Jacket (FPJ) is a design concept featuring a thick, tough jacket that covers the entire profile of the bullet. Intended for maximum momentum transfer to steel targets, this design generates good dwell time on the target for maximum “push.” The heavy base is fully enclosed to withstand the high pressures of magnum loads and maintain “match” accuracy. The unique upset qualities of this design and strict dimensional tolerances combine to provide unsurpassed accuracy and performance. The FPJ design is a silhouette bullet with some hunting applications where deep penetration and minimal expansion are desired.
Full Metal Jacket (FMJ) is a traditional design configuration featuring traditional Sierra accuracy and quality. Designed for flawless feeding characteristics in semi-automatic pistols, it is also recognized for its deep penetration due to its heavy jacket. Although nose configurations and ogives were designed for positive feed in auto-loading pistols, Sierra’s strict quality control and dimensional controls result in an exceptionally accurate bullet. Unlike other FMJ designs, the Sierra bullet is capable of match accuracy as well as flawless feeding for the utmost in shooter confidence. It is an excellent choice for combat or speed type competitive shooting situations.
