Since 1939, more hunters have relied on Remington Core-Lokt than any other big game ammunition, and rightly so. It’s filled more tags on more continents than any other load. Core-Lokt is the original controlled expansion bullet. Its time-proven performance has made it hunting’s first choice for over 75 years. The tapered copper jacket is locked to a solid lead core delivering massive 2X expansion, weight retention and consistent on-game results.SpecificationsCaliber: 270 WINGrains: 150Type: Core-Lokt SPMuzzle Velocity: 2850 fpsVelocity @ 100 Yards: 2504 fpsVelocity @ 200 Yards: 2183 fpsVelocity @ 300 Yards: 1886 fpsVelocity @ 400 Yards: 1618 fpsVelocity @ 500 Yards: 1385 fpsBox of 20 (10 boxes per case)
