Sierra Bullets Expands MatchKing-X Series with New 7mm 175-Grain HPBT Projectile

Author: | Publish Date: Oct 06, 2025 | Fact checked by: Marko Lalovic

Sierra Bullets has announced the latest addition to its MatchKing-X (MKX) product family: a 7mm 175-grain HPBT bullet specifically engineered for hunting applications. The projectile is currently available through authorized dealers and online retailers.

Building on a Legacy of Precision

The MatchKing-X series represents an evolution of Sierra's renowned MatchKing platform, which has long been recognized for exceptional accuracy. Introduced in April, the MKX line distinguishes itself by incorporating controlled expansion technology, enhancing terminal ballistics even when impact velocities are reduced. This latest 7mm offering follows the recent launch of the 6mm 107-grain HPBT MKX, providing precision-oriented hunters and competitive shooters with additional caliber options.

A Purpose-Driven Design for Modern Cartridges

According to Colby Adamek, Marketing Manager at Sierra Bullets, the development of this projectile addresses specific market demand. "This bullet isn't just another addition – it rounds out the MKX family with a modern, heavy-for-caliber design that is a perfect fit for the 7mm PRC and other popular 7mm cartridges," Adamek stated. "Shooters have been asking for this bullet, and we've poured extensive testing and refinement into making sure it delivers on every front. This result is a projectile that embodies what the MKX line stands for: match-grade accuracy, relentless consistency and devastating hunting performance at long range."

Optimized for Long-Range Applications

The 7mm 175-grain HPBT MKX has been specifically engineered as an ideal companion for the 7mm PRC cartridge. Its design emphasizes controlled expansion at reduced impact velocities, making it particularly well-suited for extended-range shooting scenarios. The bullet combines match-grade precision with hunting-focused terminal performance, delivering reliable expansion characteristics while maintaining the accuracy standards expected from Sierra's competition-proven lineage.
