MAXIM 8.6 BLK 285GR TUI SBA 20/200

Short-barrel rifles deliver speed and handling in tight spaces, but they're often hamstrung by velocity loss over distance. The Maxim Defense 8.6 Blackout 285-grain ammunition bridges that gap, engineered specifically for SBR platforms in partnership with Fort Scott Munitions. What sets this round apart is the TUI (Tumble Upon Impact) projectile design—a terminal ballistics technology that creates devastating wound cavities by causing the bullet to tumble throughout its velocity range down to 500 fps. That means consistent, predictable performance whether you're working within 100 yards or stretching shots downrange.

The 285-grain bullet weight in 8.6 Blackout is a proven sweet spot for SBR ballistics, and Maxim's load optimization ensures you're getting the velocity and energy your short barrel can actually deliver. If you run an 8.6 BLK SBR for hunting, home defense, or precision rifle work, this ammunition is purpose-built for your platform—not a generic rifle round forced to work in a specialized application.

Each box contains 20 rounds, so you get a practical quantity for testing at the range or field work. Maxim Defense ammunition is made to exacting standards, and the TUI technology delivers terminal performance that exceeds traditional expanding and fragmenting projectile designs. For shooters who demand reliability and lethality from a short-barrel 8.6 Blackout, this is the real deal.
