The Sierra 1570 MatchKing 6mm .243 107gr HPBT bullet is a match-grade rifle projectile built for precision shooters who demand consistency and accuracy above all else. These hollow-point boat-tail rounds have earned their reputation in competitive disciplines that require extreme accuracy at distance—from National Match High Power to silhouette competition—where record-setting performance and national championships hang on minimal margin of error. Each box contains 100 bullets, giving you plenty of volume for load development and practice without breaking your reloading rhythm.

MatchKing bullets are engineered for benchrest-grade precision, not hunting. Their design prioritizes ballistic consistency and downrange accuracy rather than rapid expansion on game. If you're loading for varmint work, Sierra's Hornet Blitz or Varminter lines will deliver more reliable explosive expansion. But if your goal is competitive shooting, long-range target work, or precision rifle builds where every tenth of a minute of angle matters, the 107gr MatchKing remains a proven choice trusted by competitors worldwide.

One critical spec to confirm before you load: your rifle barrel must have a twist rate of 1:8 or faster to properly stabilize these projectiles. Check your barrel specs or contact the manufacturer if you're unsure; an under-twisted barrel will rob you of the accuracy these bullets are designed to deliver. Once you've verified compatibility, you've got a component that's stood the test of time in some of the most demanding shooting sports on the calendar.
