Maxim Defense 8.6 Blackout 235gr Solid Copper TUI - Box of 20

Maxim Defense 8.6 Blackout 235gr TUI puts the hard-barrier penetration and devastating soft-tissue disruption of the Tumble Upon Impact system into the 8.6 BLK cartridge at supersonic velocities, giving hunters and serious shooters a large-caliber lead-free round engineered specifically for the short-barrel, fast-twist 8.6 Blackout platform. Built for hard use, this round delivers the terminal authority the 8.6 BLK was designed to provide.

Maxim Defense 8.6 Blackout 235gr TUI is match-grade ammunition featuring a 235-grain Solid Copper Spun projectile with patented Tumble Upon Impact technology, loaded to 1,600 fps from a 12-inch, 1:3-twist test barrel.

The 235-grain SCS projectile penetrates hard barriers including bone before tumbling rapidly in soft tissue, generating a large wound channel through aggressive internal disruption. CNC-machined to match-grade tolerances for consistent accuracy across the box. Optimization for the 12-inch test barrel and 1:3 twist ensures proper projectile stabilization from short-barrel 8.6 BLK rifles.
