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 represents a proven solution 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 maintained their reputation among serious hunters who refuse to compromise on reliability or terminal performance. The 50-round box format provides shooters with sufficient ammunition for load development, practice, and field application without excessive bulk.

The 130-grain Grand Slam design features a copper-jacket construction bonded to a lead core, ensuring superior weight retention through tough hide and bone. This bonded-core architecture prevents jacket separation and core fragmentation, delivering deeper penetration and consistent energy transfer to vital zones. The boat-tail configuration reduces drag and improves ballistic coefficient, critical for .270 Winchester applications where velocity decay over distance directly impacts terminal performance and accuracy consistency. 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 controlled expansion over maximum velocity. The 50-count packaging is ideal for those developing match-grade hunting loads or maintaining consistent performance across multiple seasons. Reloaders appreciate the consistent bullet geometry and readily available load data from major powder manufacturers.
