Fort Scott Munitions TUI 9mm 115gr Solid Copper Spun Ammo 20rd

The Fort Scott Munitions TUI (Tumble Upon Impact) 9mm ammunition delivers controlled expansion and devastating terminal performance through its innovative solid copper spun design. This 115-grain load creates a tumbling effect upon impact that maximizes energy transfer while maintaining structural integrity.

What Makes This Different

Unlike traditional hollow point bullets that rely on expansion, the TUI design uses a solid copper construction with precision-machined geometry that causes the projectile to tumble end-over-end upon impact. This tumbling action creates a larger wound channel while maintaining bullet weight retention of nearly 100%. The solid copper construction eliminates lead fouling and reduces barrel wear compared to conventional jacketed bullets.

Key Features

• 115-grain solid copper spun bullet with tumble-upon-impact design
• Nickel-plated brass cases for enhanced feeding and extraction
• Consistent 1,150 fps muzzle velocity from 4-inch barrels
• 100% copper construction eliminates lead exposure concerns
• Precision CNC-machined projectiles for consistent performance
• Compatible with all 9mm Luger firearms and magazines
• Low-flash powder formulation reduces muzzle signature

This ammunition excels in defensive applications where reliable expansion and deep penetration are critical. The tumbling action begins immediately upon impact with soft tissue, creating effective stopping power while reducing over-penetration risks. Law enforcement agencies have adopted TUI technology for duty use due to its consistent performance through barriers including clothing, drywall, and automotive glass.
