Sierra MatchKing 6.5mm 142 Grain HPBT Bullets - 264 Caliber (100 Count)

The Sierra MatchKing 6.5mm 142 grain HPBT bullets are purpose-built for competitive shooters and long-range precision work in 6.5x55mm and other .264 caliber cartridges. These bullets have earned their reputation across competitive HighPower, Silhouette, and precision rifle disciplines, with a design that prioritizes match-grade accuracy and ballistic performance in controlled shooting environments.

The 142 grain MatchKing features a longer ogive radius compared to lighter 6.5mm options, which translates to a higher ballistic coefficient and reduced sensitivity to crosswind drift—valuable characteristics when you're chasing tight groups at distance. Each box contains 100 projectiles, giving you plenty of rounds for load development, competition prep, or extended practice sessions. These bullets are produced to Sierra's exacting tolerances and are recognized worldwide for delivering the consistency competitive shooters demand.

It's important to note that MatchKing bullets are engineered for target shooting and precision rifle applications, not hunting. Their design prioritizes accuracy over expansion, and they won't deliver the same performance characteristics as hunting-specific bullets. If your focus is varmint or game hunting, Sierra's Hornet Blitz or Varminter lines are better suited to the task. For reloading, you'll need a barrel with a 1:8" twist rate or faster to stabilize these projectiles effectively.

Whether you're working up loads for competition, practicing for precision rifle events, or pushing your 6.5mm rifle's accuracy potential, these match-grade bullets give you the foundation to achieve consistent, exceptional results downrange.

Frequently Asked Questions

What rifles and cartridges do these 6.5mm bullets work in?

The 142 grain Sierra MatchKing is designed for .264 caliber barrels. It's widely used in 6.5x55mm Swedish Mauser and other 6.5mm rifle cartridges. Verify that your specific cartridge uses a .264 inch bullet diameter before purchasing, and confirm your barrel twist rate meets the 1:8" minimum requirement.

Can I use these bullets for hunting?

MatchKing bullets are not recommended for hunting applications. They're engineered for accuracy and target work, not for reliable expansion on game. Sierra produces purpose-built hunting bullets in other product lines that will perform much better for that application.

What barrel twist rate do I need?

Your rifle barrel must have a 1:8" twist rate or faster to properly stabilize the 142 grain MatchKing. Slower twist rates may result in accuracy issues or keyholing. Check your rifle's specifications before reloading.

How many bullets are in a box?

Each box contains 100 Sierra MatchKing bullets, giving you a full supply for load development, competition testing, or extended practice sessions.
