About Total Metal Case (TMC) Ammunition

These loadings feature bullets with complete metal encasement designed to eliminate lead exposure while providing enhanced visibility through tracer-like technology. Developed by manufacturers like Ammo Inc. for their STREAK product line, the Total Metal Case bullet incorporates a complete metal jacket that fully encases the lead core while often featuring specialized coatings or compounds that create visible trace effects without traditional tracer components. The TMC design provides reduced lead exposure and enhanced training feedback while maintaining reliable feeding and consistent ballistic performance. These types of loadings are well-suited for training applications and range shooting where reduced lead exposure, visual feedback, and reliable performance are desired for enhanced training effectiveness and environmental considerations.

Common Total Metal Case (TMC) Calibers

• 9mm:The 9mm Luger cartridge is easily the most common handgun round in common use. The caliber goes by many names, often being referred to as 9mm NATO, 9mm Parabellum, 9x19mm, or just generically “9mm”. The cartridge’s origins can be traced back to the early 20th century and is the brainchild of Georg Luger. Originally found in firearms such as the Borchardt C-93 and the P-08 Luger pistol, the round has become a common chambering for handguns in civilian and military use from the 20th century onward. Firearms such as pistols and submachine guns in 9mm Luger have commonly been used by military and law enforcement personnel across the globe, leading to the round establishing a reputation for being a reliable service cartridge.
• .380 ACP:The .380 ACP, or .380 Automatic Colt Pistol, was designed by John Moses Browning in 1908. Production of the cartridge began in the same year and saw immediate use in Colt’s Model 1903 Pocket Hammerless handgun. The .380 ACP was derived from the .38 ACP, or .38 Auto cartridge which was introduced in 1900 by Browning. Since its introduction, the cartridge has been used in a variety of firearms such as handguns for concealed carry and even submachine guns. Today, the cartridge is still utilized for defensive purposes and benefits from modern, optimized loadings which increase the effectiveness of the round.
• .44 Magnum:The .44 Magnum was developed by Elmer Keith and Smith & Wesson in the 1950s alongside the Model 29 revolver. Known for its powerful recoil and impressive stopping power, the .44 Magnum was popularized in mainstream culture through films like Dirty Harry. Today, it remains a popular choice for handgun hunting, plinking, and self-defense.
• .38 Special:The .38 Special cartridge was developed by Smith & Wesson in 1898 and has a long history as a reliable round for law enforcement, self-defense, and target shooting. Known for its manageable recoil and effectiveness, it became one of the most widely used revolver cartridges in the 20th century. Even today, it remains a staple among revolver enthusiasts and is commonly found in both new and vintage handguns.
• 10mm:The 10mm Auto, often referred to as 10mm, is a potent handgun cartridge that was introduced in 1983. When compared to standard, non-specialty .357 Magnum loadings, the 10mm Auto is capable of producing higher energies. Specialty 10mm Auto loadings are on par with specialty, high performance .357 Magnum loadings. The cartridge is often compared to the 9mm Luger and .45 ACP as they are common semi-automatic cartridges of the time. The 10mm Auto essentially has high velocities, like 9mm Luger, and larger, heavier projectiles, like .45 ACP, providing shooters with a versatile and capable round. The 10mm Auto will notably have a stout and snappy recoil impulse which is accompanied by flat trajectories.
