The 6mm 95 grain Hollow Point Boat Tail bullet was designed to fill the need for a lighter weight alternative to the Sierra 6mm 107 MatchKing. This bullet is a popular choice for across the course and long range target customers. Sierra built this bullet off our ever popular 6mm 107 HPBT MatchKing design with a long ogive, small meplat and improved boat tail to preserve downrange efficiency, enhance accuracy, and reduce wind-drift. 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 or VarmintKing counterparts. This bullet requires a barrel twist rate of 1×9” or faster. The #1537 was introduced in 2008.
