The Sierra 1570MP MatchKing is a 6mm 107-grain hollow point boat tail rifle bullet engineered for competitive precision shooting and target work. This closed-nose HPBT design has earned its reputation across national championships and record-setting competitions—from High Power matches to silhouette events—where nothing less than extreme accuracy at distance will win. If you're handloading ammunition for competition or serious long-range target shooting, the MatchKing's proven ballistics and consistency make it a go-to choice for shooters who demand repeatable, sub-MOA performance.
Sierra's MatchKing bullets are built to exacting tolerances for minimal run-out and maximum BC stability in flight. The 107-grain 6mm version delivers a G1 ballistic coefficient of 0.547 and G7 BC of 0.262, supporting flat trajectories and reliable wind-resistance across competitive distances. These are purpose-built match bullets—not hunting rounds—and they're not recommended for most game applications. If you're planning varmint work, Sierra's Hornet or Varminter line will deliver more consistent expansion. One important note: the 1570MP requires a barrel twist rate of 1:8 or faster to stabilize properly, so verify your rifle's twist before ordering.
Each box contains 250 bullets, making bulk loading for a season of competition practical and economical. Consistency across 250 rounds means your load development data holds true, and you'll spend more time at the range and less time chasing fliers. Whether you're preparing for a national-level match or zeroing in a precision rifle, these bullets give you a platform trusted by competitive shooters across disciplines.

Frequently Asked Questions
What barrel twist do I need for the Sierra 1570MP?
The 1570MP requires a barrel twist rate of 1:8 or faster for proper stabilization. If your rifle has a slower twist (like 1:9 or 1:10), these bullets may not perform as intended. Check your rifle's specifications before purchasing.
Are these MatchKing bullets suitable for hunting?
No. Sierra MatchKing bullets are designed and recommended for competition and target shooting, not hunting. Their design does not provide the reliable expansion needed for game animals. For varmint hunting, Sierra offers their Hornet or Varminter line with better expansion characteristics.
How many rounds are in a box?
Each box of Sierra 1570MP MatchKings contains 250 bullets, making it convenient for handloaders to prepare match-grade ammunition in bulk.
What makes these bullets accurate for competition?
The MatchKing's hollow point boat tail design, combined with Sierra's tight manufacturing tolerances and closed-nose construction, minimizes bearing surface variation. This consistency translates to minimal velocity spread and run-out in your finished ammunition, which is essential for competitive precision at long range.
