The Sierra MatchKing 7mm (.284) 175 Grain HPBT bullets are built around one principle: sub-MOA precision at distance. These hollow-point boat-tail rounds are engineered for serious long-range target shooters and precision reloaders who demand consistency shot after shot. Each box of 100 delivers the meticulous construction that has made MatchKing the go-to choice for competitive shooters and record-setters worldwide.
What separates MatchKing from run-of-the-mill target ammo is obsessive attention to manufacturing tolerances. The jackets are drawn to a concentricity standard of just 0.0003 inch maximum variation—tight enough to eliminate the subtle wobbles that throw cold shots off target. Individual bullets are weighed to within ±0.3 grain, so your load data stays valid across the entire box. That consistency translates directly to tighter groups and more reliable ballistic performance downrange.
The 175-grain weight in 7mm (.284 diameter) offers a high ballistic coefficient thanks to the small hollow-point meplat and boat-tail design, minimizing drag and drift in crosswinds. Whether you're load development at the bench or chasing group records on the line, these bullets reward precision reloading with precision results. Note that MatchKing bullets are purpose-built for target shooting; they are not recommended for hunting applications.

Frequently Asked Questions
What rifles and cartridges can I load these bullets in?
The Sierra MatchKing 7mm (.284) 175 grain bullets are designed for 7mm cartridges that accept .284 diameter projectiles, such as 7mm Remington Magnum, 7mm-08 Remington, and other standard 7mm rifle cartridges. Always consult published reloading data for your specific cartridge before beginning load development.
Are these bullets suitable for hunting?
No. Sierra MatchKing bullets are purpose-built for target shooting and precision rifle competition. They are not recommended for hunting applications.
What makes MatchKing bullets more accurate than standard bullets?
MatchKing bullets achieve their accuracy reputation through extremely tight manufacturing tolerances: jacket concentricity of 0.0003 inch maximum variation and individual weight tolerance of ±0.3 grain. These tolerances minimize inconsistencies that would otherwise cause vertical and horizontal spread. The boat-tail hollow-point design also provides a high ballistic coefficient for stable, predictable flight.
