.243 | 100gr | Speer Grand Slam
by Speer · See details on brand website
The Speer Grand Slam is a premium hunting bullet designed for deep penetration on large, tough game. Its unique two-core construction features a front lead core for controlled expansion and a rear core that remains intact for maximum weight retention and penetration. The thick copper jacket and cross-member partition ensure the bullet holds together during impact with heavy bone and muscle. This design makes the Grand Slam particularly effective on elk, moose, and large African game where penetration is critical. Handloaders appreciate its consistent performance and ability to anchor large animals with proper shot placement.
