MAXIM 8.6 BLK 235GR TUI SBA 20/200

Short-barrel rifles demand ammunition engineered for their unique ballistic reality. The Maxim Defense 8.6 Blackout 235gr TUI round bridges that gap—purpose-built in partnership with Fort Scott Munitions to deliver terminal performance from the velocities you actually get downrange when running a compact rifle. Unlike factory loads optimized for 16-inch barrels, this 8.6 Blackout round is tuned specifically for short-barreled rifles and their ballistic envelope, so you get consistent, predictable wound ballistics instead of compromised performance.

The heart of this load is Maxim Defense's TUI (Tumble Upon Impact) bullet technology. The 235-grain projectile is designed to tumble through the target down to 500 fps, creating ballistic wound cavities that exceed the performance standards of conventional expanding and fragmenting designs. That tumbling action transforms the bullet's trajectory into devastating terminal effect—the kind of physics that matters when distance and barrel length are working against you.

Each box contains 20 rounds, making it easy to stock up for practice, testing, or duty use without waste. Whether you're running an 8.6 Blackout SBR for home defense, close-quarters hunting, or tactical applications, this Maxim Defense ammunition was engineered to make that short barrel perform like it should.

Frequently Asked Questions

What ammunition works in short-barrel 8.6 Blackout rifles?

The Maxim Defense 8.6 Blackout 235gr TUI round is specifically engineered for short-barrel rifles. It's load-optimized to deliver terminal ballistics consistent with SBR velocities, unlike standard full-length rifle ammunition.

How does TUI (Tumble Upon Impact) technology work?

The TUI bullet is designed to tumble through the target all the way down to 500 fps, creating wound cavities that exceed the performance of conventional expanding and fragmenting projectiles. That tumbling action generates superior terminal effect even at shorter barrel velocities.

How many rounds come in a box?

Each box contains 20 rounds, allowing you to test the load or keep your magazines supplied without oversized packaging.

Is this ammunition suitable for hunting?

The Maxim Defense 8.6 Blackout TUI round was engineered for close-quarters applications where short-barrel rifles excel. Its terminal ballistics design is appropriate for hunting where 8.6 Blackout is legal, though you should verify local regulations and game-specific requirements for your specific use.
