The Sierra MatchKing-X 7mm 175gr HPBT (Sierra part no. 1976C) brings Sierra’s long-running MatchKing accuracy pedigree to a homogeneous, all-copper design for handloaders who want match-level consistency at the reloading bench. Sierra has built these bullets for precision rifle shooters who demand tight, repeatable groups from a boat-tail hollow point profile. Sold in a bulk 500-count box, this .284-caliber bullet is built for reloaders running high volumes through a 7mm precision or long-range rifle. It’s a straightforward choice for anyone standardizing their load development around a proven bullet weight and profile.
