Sierra Bullets 6Mm 107Gr Tmk Tipped Matchking 100/Box

The Sierra Bullets 6mm 107gr Tipped MatchKing is a precision rifle bullet designed for target shooters and long-range competitors who demand consistent, record-setting accuracy. Built on Sierra's legendary MatchKing heritage, the TMK adds a polymer tip that reduces aerodynamic drag and boosts ballistic coefficient—translating to flatter trajectories and more predictable wind drift at distance. The tipped design also improves feeding reliability in magazine-fed platforms, eliminating the feeding inconsistencies that can plague traditional match bullets.

These are engineered for match competition and precision rifle disciplines where downrange stability and velocity retention matter. The 0.574 G1 ballistic coefficient (or 0.292 G7) makes the 107gr TMK competitive in long-range rifle applications. However, Sierra explicitly notes that TMK bullets are not recommended for most hunting; their construction prioritizes accuracy and aerodynamics over expansion, so they lack the consistent, reliable expansion of dedicated hunting or varmint designs.

One critical spec: your rifle needs a barrel twist of 1:8 or faster to stabilize this bullet safely and accurately. This heavier 6mm projectile demands sufficient rotational velocity. If you're reloading for a precision rifle, PRS competition, or dedicated range work and your barrel meets that twist requirement, the 107gr TMK delivers the ballistic performance Sierra bullets are known for. Each box contains 100 bullets, so you've got plenty for load development and match prep.

Key Features

Frequently Asked Questions

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

Your rifle requires a minimum barrel twist rate of 1:8 or faster. This heavier bullet demands sufficient rotational velocity for proper stabilization. If your barrel is slower than 1:8, this bullet is not suitable for your rifle.

Is this bullet suitable for hunting?

No. Sierra does not recommend the Tipped MatchKing for most hunting applications. These bullets are engineered for target shooting and precision rifle competition. Their construction does not deliver the consistent expansion at comparable velocities that dedicated hunting rounds provide. If you're hunting, look to Sierra's HuntKing or VarmintKing lines instead.

How many bullets are in a box?

Each box contains 100 Sierra 6mm 107gr Tipped MatchKing bullets.

What makes the tipped design different from a standard MatchKing?

The polymer tip reduces aerodynamic drag, which improves ballistic coefficient and downrange stability. The tip also promotes more reliable feeding in magazine-fed firearms compared to traditional flat-nose MatchKing designs.
