MatchKing Target Design
The MatchKing line is Sierra's target-oriented bullet family, and this 107-grain 6mm version uses a hollow point boat tail profile. Its published ballistic data and 107-grain weight provide useful specifications for shooters comparing 6mm match projectiles. Any barrel-twist recommendations for this bullet should be referenced directly from current Sierra technical information for the specific application.
Ballistic Data
Sierra publishes velocity-dependent G1 ballistic coefficient information for this projectile rather than representing its aerodynamic performance with a single value across all velocities. The listed G1 coefficient is 0.547 at 2400 fps and above and 0.536 between 1800 and 2400 fps. These figures should be treated as manufacturer ballistic reference data rather than loading instructions.
Component Identification
This product contains component bullets only and is not loaded ammunition. Cartridge components should be identified by their exact manufacturer part number, bullet diameter, weight and construction. Any assembly or loading information should be obtained from current authoritative reloading data applicable to the specific cartridge, firearm and components being used.
