Sierra Bullets 6Mm 107Gr Tmk Tipped Matchking 500/Box

The Sierra Bullets 6mm 107gr Tipped MatchKing (TMK) is a match-grade rifle bullet engineered for precision target shooting and competitive reloaders who demand flat trajectories and consistent downrange performance. By pairing Sierra's legendary MatchKing accuracy with an acetal resin tip, the TMK line reduces aerodynamic drag and delivers a ballistic coefficient that keeps your rounds flying true at distance—all while promoting smooth, reliable feeding in magazine-fed rifles.

This 500-round box of 107-grain 6mm projectiles carries a G1 ballistic coefficient of 0.574 (G7: 0.292), meaning less drop and wind drift on shots beyond 300 yards. The tipped design is the differentiator here: Sierra added it specifically to improve downrange ballistics and chamber feeding reliability compared to untipped MatchKing variants. If you're handloading for a precision rifle platform—whether a bolt-action target gun or a magazine-fed tactical build—these bullets reward consistent powder charges, quality brass, and good technique with the accuracy Sierra is known for worldwide.

Important to note: TMK bullets are purpose-built for match and target use. While some reloaders do use them for varmint hunting, their construction doesn't provide the consistent, rapid expansion you'd get from purpose-designed hunting or varmint projectiles at typical hunting velocities. They're a match-grade tool for distance shooting, not a general-purpose hunting round. You'll also need a barrel twist rate of 1:8 or faster to stabilize the 107-grain bullet properly.

Frequently Asked Questions

What barrel twist rate do I need for the 6mm 107gr TMK?

A twist rate of 1:8 or faster is required to properly stabilize the 107-grain bullet in flight. If your rifle has a slower twist (like 1:9 or 1:10), you may experience accuracy issues or instability downrange.

Can I use these bullets for hunting?

TMK bullets are engineered for target and match shooting, not hunting. While some reloaders have used them for varmint work, they lack the construction needed for consistent, reliable expansion at hunting velocities. For hunting applications, Sierra offers other bullet lines like VarmintKing or Hornet Blitz that are purpose-designed for that use.

What makes the Tipped MatchKing different from the standard MatchKing?

The acetal resin tip reduces aerodynamic drag, improving the ballistic coefficient and delivering flatter, more predictable trajectories downrange. The tip also helps ensure smooth, reliable feeding in magazine-fed rifles, making the TMK a better choice for modern tactical and competition platforms.

How many bullets are in a box?

Each box contains 500 Sierra 6mm 107gr TMK bullets, providing ample supply for load development, practice sessions, and match preparation.
