Product Overview

THE DEADLIEST MUSHROOM IN THE WOODS FOR MORE THAN 75 YEARS.

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. Available in soft point and pointed soft point versions, and in a range of bullet weights for virtually every centerfire hunting caliber made. Trust your next hunt to the best-selling hunting ammunition of all time.
