SIERRA BULLETS
The Sierra MatchKing 30 Cal 155gr HPBT Bullets are built for shooters who refuse to compromise on precision. These .308 diameter rifle bullets represent Sierra's decades of experience in match-grade ammunition design, engineered from the ground up to deliver the accuracy that competitive shooters and long-range reloaders demand. Whether you're working up loads for a regional match, testing a new rifle build, or pushing the limits of your setup at 600+ yards, these bullets are purpose-built to perform when precision matters most.
What makes MatchKing bullets legendary among precision shooters is the obsessive attention to manufacturing tolerances. The jacket concentricity is held to 0.0003 inch maximum variation—tight enough that bullet runout won't mask your reloading technique. Weight consistency stays within ±0.3 grain per bullet, which matters when you're chasing sub-MOA groups. That uniformity translates directly to predictable ballistic performance and tighter shot grouping, shot after shot.
The 155 grain weight in .308 diameter sits in a sweet spot for mid-range to extended-distance rifle work. The hollow point boat tail design minimizes air drag and boosts ballistic coefficient, helping your rounds retain velocity and energy downrange. The small meplat (the flat tip of the hollow point) is precisely engineered to support that ballistic profile. This is match-grade ammunition for match-grade results.
One important note: Sierra MatchKing bullets are optimized for target and competition use. They're not recommended for hunting applications. If you're a reloader focused on accuracy—whether you're running a bolt-action precision rifle, competing in sanctioned events, or simply holding yourself to the highest standard—these bullets belong in your brass.
| Caliber | 30 Cal / .308 Diameter |
| Weight | 155 grains (±0.3 grain tolerance) |
| Bullet Type | Hollow Point Boat Tail (HPBT) |
| Jacket Concentricity | 0.0003 inch maximum variation |
| Design Classification | MatchKing (Sierra Target/Match Grade) |
The .308 diameter makes these bullets compatible with .308 Winchester, .300 Winchester Magnum, .300 Blackout, and other cartridges that use .308 diameter projectiles. Always verify your specific cartridge and rifle combination before loading, and consult published reloading data for your exact powder and primer combination.
Sierra does not recommend MatchKing bullets for hunting applications. These bullets are designed and optimized for target and competition shooting. If you're planning to hunt, consider Sierra's other bullet lines engineered specifically for field use.
The extreme tolerances on jacket concentricity (0.0003 inch) and weight (±0.3 grain) mean each bullet behaves identically in flight. The boat tail design and optimized hollow point keep aerodynamic drag predictable and ballistic coefficient high. When combined with careful reloading practices, these tight tolerances let your technique—not bullet variation—determine your groups.
Yes. The 155 grain weight and boat tail design are well-suited to mid-range and extended-distance precision rifle work. The high ballistic coefficient helps retain velocity and energy downrange, supporting the flat trajectory and consistency that long-range shooters value.
