Sierra MatchKing 223 Remington ammunition (part no. A937709F) loads the legendary 77-grain HPBT MatchKing bullet in a limited run built to support the Folds of Honor foundation. Sierra has spent nearly 75 years refining the MatchKing’s boat-tail profile and hollow-point tip, and this run pairs it with match-grade brass, primers, and powder so the ammunition shoots to the same standard competitors have trusted for decades. A percentage of every box sold helps fund scholarships for the families of wounded or fallen military members and first responders. For rifle ammunition built for the precision shooter who also wants their purchase to mean something, this is the box worth buying.
