Remington UMC 357 SIG 125gr FMJ Ammunition - 50 Rounds

The Remington UMC 357 SIG 125gr Full Metal Jacket ammunition delivers consistent performance for training and target shooting applications. This high-velocity cartridge combines the stopping power of a .357 Magnum with the feeding reliability of a semi-automatic platform. Law enforcement agencies and competitive shooters rely on this load for its predictable ballistics and clean-burning powder.

What Makes This Different

Remington's UMC (Union Metallic Cartridge) line represents over 200 years of ammunition manufacturing expertise. The 125-grain FMJ projectile achieves approximately 1,350 fps muzzle velocity, generating 506 ft-lbs of energy. This load maintains tighter shot groups than many competing brands while producing minimal barrel fouling. The brass cases feature consistent wall thickness for reliable extraction and potential reloading.

Key Features

• 125-grain Full Metal Jacket bullet for deep penetration and minimal expansion
• High-velocity 357 SIG chambering with approximately 1,350 fps muzzle velocity
• Clean-burning powder reduces fouling and extends cleaning intervals
• Boxer-primed brass cases suitable for reloading applications
• 50-round box packaging for range training and practice sessions
• Compatible with SIG P229, P320, Glock 31/32, and other 357 SIG firearms
• Non-corrosive primers ensure long-term storage reliability

This ammunition excels in competitive shooting environments where consistent point of impact matters most. The FMJ design feeds reliably through semi-automatic actions while maintaining accuracy standards required for precision training. Indoor ranges appreciate the reduced lead exposure compared to traditional lead-nose bullets. The cartridge performs consistently across temperature ranges from -20°F to 140°F without significant velocity variations.
