Sellier & Bellot SB757B 7x57mm Mauser 140gr Soft Point ammunition is engineered to deliver reliable terminal performance for the discerning rifleman. This cartridge integrates a semi-jacketed soft point projectile designed for consistent, controlled expansion and high weight retention.
Key Features
Projectile Design
The SB757B utilizes a 140gr Semi-Jacketed Soft Point (SP) projectile. This design incorporates a lead core encapsulated by a precisely engineered copper jacket. The jacket’s geometry facilitates controlled expansion upon impact, while the robust construction ensures high weight retention, optimizing energy transfer and penetration within the target. This controlled deformation mitigates over-penetration while maximizing terminal effect.
Performance Profile
Optimized for hunting and general-purpose rifle applications, this ammunition provides a balanced trajectory and consistent terminal ballistics. The bullet’s design promotes reliable performance across a range of velocities typical for the 7x57mm Mauser cartridge.
Manufacturing Integrity
Manufactured to Sellier & Bellot’s established standards, these cartridges offer consistent primer ignition, powder burn rates, and overall cartridge integrity. This contributes to predictable performance and repeatable accuracy in various rifle platforms chambered for 7x57mm Mauser.
