Sierra
The Sierra 1575MP MatchKing 6mm 110gr hollow point boat tail rifle bullet is engineered for competitive shooters and precision reloaders who demand match-grade accuracy downrange. Loaded 250 per box, these .243-diameter projectiles deliver the consistency that's made MatchKing bullets a standard in target competitions and long-range shooting disciplines. Whether you're loading for a benchrest rifle, an F-Class platform, or a dedicated target gun, the 1575MP combines Sierra's proven design with ballistic efficiency built for minimal wind drift and velocity retention over distance.
The key to the 1575MP's reputation lies in its engineering details. A sleek 27-caliber ogive shape works with a final meplat-reducing pointing operation to maximize the ballistic coefficient—translating to flatter trajectory and more predictable wind performance. The bearing surface-to-ogive junction is ground to a 1.5-degree angle that mirrors the throat geometry of many match rifle chambers, promoting bullet-to-bore alignment for the kind of consistency that wins competitions. With a G1 BC of 0.617 and G7 BC of 0.304, these projectiles hold velocity and energy exceptionally well in the thin air above 800 yards.
Built with a jacketed lead core and a closed hollow point, the 1575MP is not designed for hunting. Sierra explicitly notes that while MatchKing bullets are sometimes used on varmints, their design prioritizes accuracy over expansion, and they will not deliver the explosive, reliable terminal performance of purpose-built hunting rounds on game. This is a match and target bullet, full stop. Note that the 1575MP requires a barrel twist rate of 1 in 7 inches or faster to stabilize properly—verify your rifle's specs before committing to a loading program.
If you're serious about reloading for precision rifle competitions, long-range target shooting, or just want the absolute most consistent, highest-BC 6mm bullet available, the Sierra MatchKing is worth the investment. Buy in bulk with the 250-round box and take advantage of their legendary consistency.
| Caliber | 6mm (.243) |
| Bullet Weight | 110 grains |
| Bullet Type | Hollow Point Boat Tail, Closed Nose (HPBT-CN) |
| Ballistic Coefficient (G1) | 0.617 |
| Ballistic Coefficient (G7) | 0.304 |
| Rounds per Box | 250 |
| Material | Jacketed Lead |
| Minimum Barrel Twist | 1 in 7 inches or faster |
| Purpose | Match/Target |
The 1575MP requires a minimum barrel twist rate of 1 in 7 inches or faster to stabilize properly. Check your rifle's specifications before developing loads; an undersized twist will result in poor accuracy and erratic performance.
No. Sierra explicitly does not recommend MatchKing bullets for hunting. While they may be used on varmints in some cases, their design prioritizes match-grade accuracy over terminal expansion, and they will not provide reliable, explosive expansion on game animals like lighter-jacketed hunting rounds do. Use purpose-built hunting bullets for ethical, effective kills.
Each box contains 250 rounds, making them convenient for serious competition shooters and reloaders who consume ammunition in volume.
The 1575MP's combination of a refined ogive shape, high ballistic coefficient (G1 BC 0.617, G7 BC 0.304), and a bearing surface-to-ogive junction ground to 1.5 degrees provides exceptional bullet-to-bore alignment and wind resistance. These design details minimize drift and velocity loss at distance, essential for competitive and precision shooting.
