That’s why GECO 9mm 115 grain TMJ ammo is so great. Unlike a standard full metal jacket, this round’s total metal jacket prevents any part of the bullet’s lead core from coming into contact with white hot exploding propellant that would have evaporated it. You’ll benefit from a flat trajectory courtesy of the round’s supersonic muzzle velocity, great accuracy as the TMJ’s profile remains undeformed throughout ignition, and no aerosolized lead from the core’s evaporation!
GECO’s TMJ contains no steel, so it’s allowed at all indoor ranges. Their ammo is also non-corrosive, and its Boxer-primed brass cases are exactly what you want for smooth feeding and extraction as well as the option to handload afterward.
Not recommended for firearms with ported barrels or compensators.
