Sierra MatchKing-X Features The Sierra MatchKing-X shares the same ogive as its traditional MatchKing counterpart meaning the near identical ballistic coefficient lets shooters use the same seating depth they are already familiar with. At 135 grains and a .277 diameter for .270 Cal rifles these hollow point boat tail bullets are held to the same tight accuracy standards that have made the MatchKing line a favorite among precision shooters. New construction methods alter the jacket mouth and nose geometry allowing the jacket to expand more rapidly on impact than a traditional match bullet. This redesign is aimed at hunters who want MatchKing level accuracy paired with more reliable terminal performance on game. A softer lead core compared to a traditional MatchKing bullet enhances expansion at the lower velocities often encountered at extended hunting ranges. This makes the MatchKing-X well suited to shooters pursuing both long range accuracy and dependable expansion when the shot presents itself in the field. Because these are component bullets handloaders retain full control over powder charge and seating depth to tune a load for their specific rifle. Packaged 500 to a box this Sierra MatchKing-X bullet is available for sale at GrabAGun for reloaders building precision hunting ammunition.
