Speer Grand Slam Rifle Bullets in 7mm .284" 160 grain GSSP design represent a time-tested hunting round built around controlled weight retention and deep penetration. Originally introduced in the 1970s, these bullets have maintained their reputation among serious hunters who demand consistent performance across varied game and distances. The 160-grain offering in 7mm caliber delivers the ballistic characteristics necessary for reliable takedown on medium to large game while maintaining the accuracy standards that competitive and field hunters expect.
The Grand Slam design features a tapered, precision-drawn jacket with internal flutes that work together to ensure consistent expansion while preserving core-to-jacket integrity throughout the penetration cycle. This construction philosophy means the bullet retains a higher percentage of its original weight compared to designs that rely on rapid fragmentation, a critical factor when terminal performance must be reliable across bone and heavy muscle. The .284" diameter specification ensures proper chambering in standard 7mm rifle platforms. At 160 grains, this bullet weight sits in the mid-range for 7mm applications, balancing recoil management with sufficient sectional density for deep, straight-line penetration on game at extended distances.
This product is packaged in a 50-round count box, a standard format for reloaders and ammunition builders who require component-level control over their finished round specifications. Hunters who handload their own ammunition benefit from Speer's consistent dimensional tolerances and proven jacket-core construction. The Grand Slam series remains competitive for hunters in 7mm who prioritize proven reliability over novelty, particularly those working within established reloading data and seeking components with documented field performance across decades of use.
