Designed for muzzleloading hunting with both modern or traditional 50 caliber rifles, Premier AccuTip MZ's muzzleloading bullets/sabots provide exceptional accuracy and dramatic performance on big game. Premier AccuTip MZ's bonded bullet is guided by the innovative Power Port(TM) Tip, the same industry-leading technology used in Remington's popular Premier AccuTip rifled shotgun slugs. On impact, the tip enables quick expansion for deadly energy transfer while the 260-grain bonded bullet provides optimal penetration and 97%+ weight retention.
