SIERRA BULLETS
The Sierra MatchKing 338 Caliber 300 Grain HPBT Bullets are purpose-built for long-range precision shooting in magnum rifle cartridges. These heavy-for-caliber projectiles carry the MatchKing pedigree—proven downrange accuracy that's earned respect from competitive shooters and handloaders pushing the limits of .338 Winchester Magnum and .338-378 Weatherby loads. At 300 grains, they deliver the ballistic stability needed for extended-range work where consistency matters more than speed.
These are match-grade bullets designed for shooters who prioritize accuracy above all else. The HPBT (hollow point boat tail) design minimizes drag and supports tight grouping at distance, making them a natural choice for long-range target work and precision rifle competition. However, it's critical to understand their intended use: MatchKing bullets are not engineered for hunting. Their design prioritizes accuracy and BC over the expansion characteristics that responsible hunting demands. They can be used for varmint work, but they won't deliver the reliable expansion you'd get from purpose-built varmint projectiles at comparable velocities.
Before committing to a batch, verify your rifle's twist rate: this bullet requires a minimum 1:10" twist barrel to shoot effectively. Undertwist barrels may struggle to stabilize the weight and length of a 300-grain projectile, resulting in precession and poor accuracy. If you're building or rebarreling for these heavy magnums, confirm your twist specification first.
| Brand | Sierra Bullets | |
| Caliber | .338 (338 Diameter) | |
| Weight | 300 Grains | |
| Bullet Type | HPBT (Hollow Point Boat Tail) | |
| Minimum Barrel Twist | 1:10" |
These are built for .338 Winchester Magnum and .338-378 Weatherby Magnum rifles. Your barrel must have a 1:10" twist rate or faster to stabilize the 300-grain projectile effectively. Slower twists risk tumbling and poor accuracy.
No. MatchKing bullets are designed for accuracy and target shooting, not for hunting. Their construction prioritizes ballistic performance and consistency over the controlled expansion needed for ethical, reliable game harvest. Use hunting-specific bullets for that purpose.
While MatchKing bullets are sometimes used for varmint work, they won't deliver the same reliable expansion as Sierra's lightly jacketed Hornet Blitz or Varminter bullets at equivalent velocities. If varmint performance is your goal, those dedicated designs are the better choice.
A minimum 1:10" twist barrel is required. Faster twists (like 1:8") work fine, but anything slower will not reliably stabilize a 300-grain projectile.
