Speer Grand Slam Rifle Bullets 7mm .284" 145 gr GSSP 50/ct

The Speer Grand Slam rifle bullet in 7mm .284" 145 gr is a proven choice for hunters who need a cartridge that handles hard-hitting game and demanding field conditions. Since their introduction in the 1970s, Grand Slam bullets have earned their reputation among serious hunters by combining reliable expansion, weight retention, and repeatable accuracy. Built with Speer's Hot Cor manufacturing process, these bullets fuse the jacket and core during production, resulting in symmetrical expansion and consistent terminal performance across a range of velocities.

What sets the Grand Slam apart is its carefully tapered, precision-drawn jacket fitted with internal flutes. This design enhances the structural integrity of the bullet while promoting controlled expansion on impact—critical when you're closing the distance on elk, deer, or other medium to large game. The jacket-and-core fusion design minimizes jacket-core separation, so you get maximum weight retention and reliable penetration when it counts.

Whether you're loading for a 7mm Remington Magnum, 7mm-08, or another 7mm cartridge, the 145-grain weight provides a solid balance of velocity retention and knockdown power. This is a bullet built for hunters who reload their own ammunition and expect their components to deliver the same performance season after season. Each box contains 50 bullets.
