Speer Total Metal Jacket Handgun Bullets
Speer's Total Metal Jacket (TMJ) bullets represent a significant advancement in handgun ammunition design. Unlike conventional full metal jacket rounds that leave lead exposed at the base, these .400 155-grain bullets employ Uni-Cor technology to completely encase the lead core in a seamless jacket.
Key Features
- Complete Lead Encasement: Molten lead is poured directly into the jacket, creating a flawless seal with no exposed lead at the base
- Superior Accuracy: The uniform construction delivers consistent performance shot after shot
- Dual Swaging Process: Bullets are swaged twice to ensure uniform heel geometry and absolute consistent diameter
- Ported Compensator Safe: Won't foul ported recoil compensators, making them ideal for competition and tactical shooters
- Pressure Resistant: Base design prevents deformation under pressure
Ideal For
These bullets are an excellent choice for reloaders working with .40 S&W and 10mm cartridges. Whether you're a competition shooter, tactical practitioner, or recreational reloader, Speer TMJ bullets deliver the cleanliness, accuracy, and consistency that serious shooters demand.
