Purpose-built for extended overall length short magnum cartridge applications and engineered around controlled feeding dynamics, stack presentation, and low-profile field integration.

Built around the 3.715" external-length AICS-pattern magazine format, the RedSnake Extended OAL AICS Magazine — WSM / SAUM provides additional internal cartridge length capacity for modern short magnum cartridges configured in long action systems while retaining a compact, flush-fit profile.

**REQUIRES LONG ACTION AICS BOTTOM METAL**

The RedSnake WSM / SAUM configuration was developed specifically around the feeding characteristics and dimensional requirements of short magnum cartridge families with .550 case head diameters operated at extended overall lengths rather than constraining cartridge seating depth to conventional short action magazine limitations. 

By optimizing internal geometry around short magnum cartridge taper, shoulder geometry, and presentation dynamics, the system promotes consistent feeding performance while supporting extended cartridge overall length configurations commonly used in modern precision and hunting rifle applications.
