Speer Grand Slam Rifle Bullets .270 cal .277" 130 gr GSSP 50/ct

Speer Grand Slam Rifle Bullets .270 cal .277" 130 gr GSSP 50/ct are designed for hunters and precision rifle shooters who demand exceptional bullet integrity and consistent performance downrange. Originally introduced in the 1970s, these bonded rifle bullets have earned a reputation among serious hunters who prioritize reliability and terminal performance.

The 130-grain Grand Slam features a copper-jacket construction bonded to a lead core, ensuring superior weight retention through tough hide and bone. This bonded construction prevents jacket separation and core fragmentation, delivering deeper penetration and consistent energy transfer to vital zones. The soft-point profile initiates controlled expansion upon impact while maintaining structural integrity for pass-through capability on larger game.

Hand-loaders and rifle hunters pursuing deer, elk, and similar game will find the .277" diameter sizing compatible with standard .270 Winchester, .270 WSM, and other .270-caliber rifle platforms. These bullets excel in custom precision loads where shooters prioritize weight retention and reliable expansion. The 50 rounds per box format provides ample ammunition for load development, practice, and field application.
