7 mm/.284 Caliber (.284) 197 gr. HPBT MatchKing
Sierra Bullets is proud to introduce a new addition to the legendary MatchKing® line. Shooters around the world will appreciate the accuracy and extreme long range performance of our new 7mm 197 grain HPBT (#1997). A sleek 27 caliber elongated ogive and a final meplat reducing operation (pointing) provide an increased ballistic coefficient for optimal wind resistance and velocity retention. To ensure precise bullet to bore alignment, a unique bearing surface to ogive junction uses the same 1.5 degree angle commonly found in many match rifle chamber throats.
While they are recognized around the world for record-setting accuracy, MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications. Although MatchKing® and Tipped MatchKing® bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz BlitzKing, or Varminter counterparts.
This bullet requires a barrel twist rate of 1×7.5” or faster.
This bullet was introduced in January 2017.
