SinterFire SF10125SD 10mm Auto 125gr Frangible Hollow Point Ammo

The SinterFire SF10125SD Special Duty ammunition delivers lead-free frangible performance designed for training environments and close-quarters applications. This 10mm Auto cartridge combines 125-grain hollow point construction with compressed copper-tin powder technology that fragments upon impact with hard surfaces while maintaining terminal effectiveness on soft targets.

What Makes This Different

Unlike traditional lead-core ammunition, the SF10125SD uses compressed metal powder that disintegrates when striking steel targets or concrete backstops at velocities above 2,000 fps. This frangible design reduces ricochet hazards and eliminates lead contamination in indoor ranges. The hollow point configuration provides controlled expansion in ballistic gelatin while the copper-tin matrix ensures consistent fragmentation patterns.

Key Features

• 125-grain frangible hollow point bullet eliminates lead exposure
• Compressed copper-tin powder construction fragments on hard surfaces
• Reduced ricochet risk for close-quarters training scenarios
• Standard 10mm Auto dimensions fit all factory chambers
• Boxer-primed brass cases suitable for reloading
• Muzzle velocity approximately 1,200 fps from 5-inch barrel
• 20-round boxes packaged in 10-box cases (200 total rounds)

Range officers and tactical instructors favor frangible ammunition for shoot house training and steel target competitions where safety margins matter. The SF10125SD maintains consistent accuracy at typical training distances while fragmenting predictably against hard barriers. Indoor ranges benefit from reduced ventilation requirements due to the lead-free composition, while the hollow point design provides realistic terminal ballistics for defensive training scenarios.
