Sierra 7mm 183 Gr MatchKing Bullets 500 Ct Shooters around the world will appreciate the accuracy and extreme long range performance of Sierra's 7mm 183 grain HPBT (#1983). 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 match rifle chamber throats. While they are recognized around the world for record-setting accuracy, MatchKingA(R) and Tipped MatchKingA(R) bullets are not recommended for most hunting applications. Although MatchKingA(R) and Tipped MatchKingA(R) 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 1A-8" or faster. This bullet was introduced in October 2015. Diameter: 0.284 Weight: 183 Gr Sectional Density: 0.324 Ballistic Coefficients and Velocity Ranges: .707 @ 2300 FPS & ABOVE .713 BETWEEN 1720 FPS & 2300 FPS .690 @ 1720 FPS & BELOW Box Count: 500 Bullets
