Sierra 7mm (.284) 175 Grain HPBT MatchKing X Bullets – 100 Count
The Sierra 7mm (.284) 175 Grain HPBT MatchKing X (MKX) combines the legendary accuracy of Sierra’s MatchKing line with dependable hunting performance. Designed as a direct counterpart to the popular 175-grain MatchKing, the MKX features the same ogive profile and external dimensions, allowing shooters to switch between target and hunting loads without changing seating die settings.
Built for hunters who demand long-range precision, the MatchKing X delivers exceptional aerodynamic performance with a G1 Ballistic Coefficient of 0.597 and G7 Ballistic Coefficient of 0.295. This streamlined design helps maintain velocity, reduce wind drift, and improve downrange consistency. Unlike traditional match bullets, the MKX is engineered to provide reliable expansion at extended hunting distances while preserving the accuracy Sierra bullets are known for.
