Ammo Inc Signature 357 Magnum 158gr TMC Ammo - 50 Round Box

The Ammo Inc Signature 357 Magnum 158gr Total Metal Case ammunition delivers consistent performance for target shooting and training applications. This precision-loaded cartridge features a 158-grain total metal case bullet that provides clean feeding and reliable extraction across a wide range of revolvers and lever-action rifles.

What Makes This Different

The Total Metal Case (TMC) construction completely encases the lead core, eliminating lead exposure at the bullet base while maintaining the ballistic characteristics of traditional jacketed bullets. Unlike standard full metal jacket rounds, the TMC design reduces lead fouling in barrels and provides cleaner burning characteristics. Each cartridge undergoes rigorous quality control testing to ensure consistent velocities within 50 fps and precise bullet seating depth.

Key Features

• 158-grain Total Metal Case bullet for reduced lead exposure and cleaner shooting
• Brass cases with consistent wall thickness for reliable reloading potential
• Non-corrosive Boxer primers for consistent ignition in all weather conditions
• Muzzle velocity of approximately 1,235 fps from 6-inch barrel revolvers
• Compatible with all .357 Magnum and .38 Special +P rated firearms
• 50 rounds per box packaging for convenient range sessions
• Manufactured to SAAMI specifications for optimal chamber fit

This ammunition performs exceptionally well in both indoor and outdoor range environments. The TMC bullet design maintains accuracy while significantly reducing airborne lead particles compared to traditional lead round nose bullets. Range officers and competitive shooters appreciate the cleaner shooting characteristics, particularly in enclosed facilities with ventilation concerns. The 158-grain weight provides excellent penetration and energy transfer, making it suitable for silhouette shooting and training applications where full-power magnum performance is required.
