The phrase “full metal jacket” is kind of inaccurate, because the jacket does not in fact fully cover the bullet’s lead core. An FMJ bullet’s core is exposed at the base, which permits hot powder gasses to evaporate lead that the shooter will breathe in – especially if they’re firing in a confined space. The “total metal jacket,” pn the other hand, is more accurately named. This 9mm round’s 115 grain TMJ projectile is 100% encapsulated by its copper alloy jacket, so no part of its lead core will ultimately find its way into your lungs.
The TMJ also avoids any deformation during ignition, hence its extremely predictable trajectory. GECO’s own high-quality brass cases, low-fouling powder and sensitive Boxer primers promote even greater accuracy. This ammo is nonmagnetic and reloadable, and its primers are sealed for added protection in storage.
We do not recommend this 9mm ammo for handguns with ported barrels or ported compensators. A port may slice off a piece of a TMJ’s jacket and deflect it back at the shooter – not pleasant if you happen to be the shooter.
