Speer Grand Slam Rifle Bullets 7mm .284" 175 gr GSSP 50/ct

Speer Grand Slam Rifle Bullets in 7mm (.284") 175 grain GSSP are engineered for hunters and precision rifle shooters who demand reliable expansion and deep penetration on medium to large game. These bonded-core projectiles represent decades of ballistic research and field-proven performance across countless hunting applications. Whether you're handloading for elk, deer, or long-range hunting scenarios, the Grand Slam delivers the terminal performance that separates ethical one-shot kills from wounded game.

The 175-grain Grand Slam features Speer's signature bonded-core construction, where the lead core is molecularly bonded to the copper jacket to ensure controlled expansion and maximum weight retention—typically retaining 90%+ of original bullet weight on impact. The soft point design initiates expansion immediately upon contact, creating a wide wound channel while the bonded core prevents fragmentation and maintains penetration through heavy bone and muscle. This dual-action mechanism ensures energy transfer is optimized for reliable takedowns at both close range and extended distances where velocity may be reduced.

Handloaders working 7mm cartridges—including the 7mm Remington Magnum, 7mm-08, and wildcats—will find the 175-grain Grand Slam ideally suited for medium to heavy game where premium bullet performance justifies the investment. The 50-round box format is standard for serious reloaders building match-grade or hunting loads. These bullets exhibit excellent accuracy potential when loaded to published specifications and seated to proper depth, making them suitable for both bolt-action rifles and lever-actions chambered in 7mm calibers where premium terminal performance is non-negotiable.
