Speer 4399 TMJ 40 S&W 155gr Total Metal Jacket Ammo 500 Rounds

The Speer 4399 TMJ delivers consistent accuracy and reduced fouling for high-volume 40 S&W shooting applications. This Total Metal Jacket ammunition eliminates lead exposure while maintaining the reliable performance Speer is known for across law enforcement and competitive shooting circles.

What Makes This Different

Total Metal Jacket construction fully encapsulates the lead core, preventing lead buildup in barrels and reducing airborne lead particles during firing. Unlike traditional full metal jacket rounds that leave the base exposed, TMJ technology covers the entire bullet surface. This design significantly extends barrel life and reduces cleaning frequency compared to standard lead-nose ammunition.

Key Features

• 155-grain Total Metal Jacket bullet with complete lead encapsulation
• 40 S&W caliber compatible with all standard 40 caliber firearms
• Boxer-primed brass cases suitable for reloading
• 500 rounds total (5 boxes of 100 rounds each)
• Consistent muzzle velocity for predictable ballistics
• Reduced barrel fouling compared to exposed lead bullets
• Clean-burning powder formulation minimizes residue

This ammunition performs reliably across various 40 S&W platforms including duty pistols, competition guns, and training firearms. The 155-grain bullet weight provides excellent accuracy while maintaining manageable recoil characteristics. Indoor range shooting benefits significantly from the reduced lead exposure, making extended practice sessions more comfortable. The consistent powder charge delivers uniform velocities shot after shot, supporting precision shooting requirements.
