Maxim 8.6 Blk 285gr Tui Sba 20/200

The Maxim 8.6 Black 285 Grain TUI ammunition delivers purpose-built terminal performance for short-barrel rifle platforms. Developed through a collaborative effort between Maxim Defense Industries and Fort Scott Munitions, this round addresses the ballistic gap inherent in SBR systems—combining optimized powder charges with controlled velocity to maintain terminal effectiveness at ranges where standard rifle ammunition loses consistency.

At 285 grains, the projectile mass is engineered for the 8.6x70mm cartridge, delivering superior sectional density and momentum retention. The TUI (Tumble Upon Impact) technology creates predictable wound cavities that exceed the terminal ballistics of both expanding and fragmenting projectiles through controlled bullet rotation post-impact. This design principle matters in defensive and duty scenarios where consistent, reliable terminal performance is non-negotiable. The round is loaded to velocities optimized for short-barrel performance, eliminating the velocity deficit that plagues standard full-power ammunition when fired from barrels under 12 inches.

This ammunition is purpose-built for operators and shooters running modern short-barrel rifle systems where barrel length sacrifices velocity but not mission requirement. Law enforcement agencies evaluating SBR platforms for tactical deployment, competition shooters optimizing ballistic performance in short-barreled builds, and defensive-minded rifle owners seeking ammunition specifically engineered for their platform will find the engineering considerations transparent and performance-driven. The 20-round packaging enables practical duty and training cycles.

The 8.6x70mm platform has gained traction among precision rifle shooters and tactical rifle communities precisely because it bridges ballistic performance gaps in shorter systems. Maxim Defense's ammunition approach reflects the industry shift toward platform-specific ammunition optimization rather than universal cartridge solutions.
