Ammo Inc's Signature .380 Auto uses a 100-grain Total Metal Coating bullet at 890 fps, producing 176 ft-lbs of muzzle energy. That's heavier and slower than most .380 range loads. The Federal American Eagle pushes a 95-grain FMJ at 980 fps for 203 ft-lbs, and the PMC Bronze runs a 90-grain FMJ at 961 fps for 185 ft-lbs. What you get with the heavier Ammo Inc load is a softer recoil impulse and reduced lead exposure from the fully encapsulated bullet.

The TMC design wraps the entire bullet, including the base, in a copper jacket. Standard FMJ rounds leave the base exposed, which allows hot gas to vaporize lead during firing. That matters most during high-volume indoor range sessions where ventilation can only do so much. The full encapsulation also tends to produce less barrel fouling than traditional jacketed bullets, so you can shoot longer between cleanings.

This round works best as affordable practice ammo for your .380 carry gun. The 100-grain weight is heavier than typical defensive loads, so it won't perfectly replicate your carry ammo's recoil. But it feeds reliably in compact pistols and gives you enough trigger time to stay sharp on fundamentals like grip pressure, sight tracking, and follow-up shot placement. If you shoot indoors regularly, the TMC design is a genuine advantage over standard FMJ options from Winchester or Fiocchi.
