Sierra Tipped MatchKing (TMK) 30 Cal 168 Grain Polymer Tip Boat Tail Bullets (.308 Diameter)

Sierra's Tipped MatchKing (TMK) 30 cal 168 grain bullets are purpose-built for precision rifle competition—particularly F-Class and 3-Gun matches where ballistic performance and consistency matter most. The defining feature of the TMK line is the acetal resin polymer tip, which reduces aerodynamic drag and raises the ballistic coefficient compared to Sierra's traditional untipped MatchKing. The result is a flatter trajectory and better energy retention downrange, enabling the 168gr TMK to maintain supersonic velocity at 1000 yards under typical .308 Winchester loads—a real advantage when every shot counts in a tight match.

These .308 diameter boat-tail bullets inherit the precision heritage Sierra built over decades with the original 168gr MatchKing, which remains the gold standard for long-range target shooting. The TMK's refined aerodynamics keep it supersonic longer, reducing wind drift and improving accuracy potential at distance. Each bullet is engineered to exacting tolerances, so you get the consistency necessary for sub-MOA groups and repeatable performance across your reloading workbench.

Important note: Sierra does not recommend MatchKing or Tipped MatchKing bullets for hunting applications. These bullets are designed for target and competition use. While they're sometimes used for varmint hunting, their match-oriented design does not deliver the same reliable, explosive expansion at hunting velocities as Sierra's specialized varmint rounds like the Hornet Blitz or Varminter line.

Frequently Asked Questions

Are these bullets good for hunting?

No. Sierra explicitly does not recommend MatchKing or Tipped MatchKing bullets for hunting. These bullets are designed for target and competition shooting. While sometimes used for varmint hunting, they do not provide reliable, explosive expansion at hunting velocities the way Sierra's specialized varmint bullets (Hornet Blitz, Varminter) do.

What's the advantage of the polymer tip over a standard MatchKing?

The acetal resin tip reduces aerodynamic drag, which raises the ballistic coefficient and improves downrange performance. This flatter trajectory and better energy retention means the 168gr TMK stays supersonic to 1000 yards at normal .308 Winchester velocities, unlike the untipped version, giving you an edge in long-range precision competition.

Will these work in my .30-06 or other .30 caliber rifle?

These are .308 diameter bullets, which are standard for most modern .30 caliber rifles including .308 Winchester, .30-06, and similar cartridges. Always verify your rifle's exact bore and chamber specifications before loading, and consult a reliable reloading manual for proper load data for your specific cartridge.

What's the typical ballistic coefficient of the 168gr TMK?

Ballistic coefficient varies with velocity: .535 at 2050 fps and above, .521 between 2050–1650 fps, and .480 at 1650 fps and below. The higher BC at higher velocities is one reason these bullets excel in long-range competition.
