Sierra MatchKing Features The Sierra MatchKing 77 grain hollow point boat tail bullet is engineered specifically for Service Rifle competition where its jacketed lead construction and boat tail design deliver the flat trajectory and consistency match shooters depend on. A G1 ballistic coefficient of 0.372 and a G7 of 0.182 keep the bullet stable and resistant to wind drift at extended ranges. The 77 grain weight was chosen so the bullet can be seated to an overall cartridge length that still cycles reliably through M16 and AR-15 magazines a critical consideration for competitors shooting from box magazines. Sierra s painstaking jacket and core construction process is what has made the MatchKing line a record holder in national competition for decades. While these bullets are optimized for paper-punching accuracy Sierra notes they are not recommended for most hunting applications due to their design priorities favoring consistency over terminal expansion. Each box contains 250 bullets giving competitive handloaders ample supply for practice and match use without frequent reordering. The .224 inch diameter matches standard .22 caliber rifle bores ensuring compatibility with the vast majority of AR-15 and bolt action rifles chambered in that bore size. For shooters chasing tighter groups and proven match performance the Sierra MatchKing 77 grain HPBT remains a trusted choice.
