The Sellier & Bellot SB757A delivers consistent performance for 7x57mm Mauser rifles with precision-manufactured 140-grain full metal jacket projectiles. This Czech-manufactured ammunition provides reliable feeding and extraction across bolt-action and semi-automatic platforms chambered in the classic 7x57mm Mauser cartridge.
What Makes This Different
Sellier & Bellot's century-plus manufacturing experience shows in the consistent powder charges and uniform bullet seating that characterize this 7x57mm load. The 140-grain weight represents the optimal balance between velocity and energy retention for the 7x57mm cartridge, delivering flatter trajectory than lighter bullets while maintaining manageable recoil. Quality control standards ensure each cartridge meets CIP specifications for European ammunition manufacturers.Key Features
