Maxim Defense .300 AAC Blackout 115gr Tumble Upon Impact (TUI) Solid Copper Spun Lead-Free 20/Box is designed to produce optimized close-quarter defense velocities and terminal performance in short barrel rifles (SBRs). SBRs sometimes lack the velocities and terminal ballistics that rifles with longer barrels produce. Maxim Defense, in partner with Fort Scott Munitions made specific adjustments to produce ammunition optimized specifically for SBRs in close-quarter, home defense and personal defense situations. This ammunition features a non-lead, Solid Copper Spun (SCS) bullet and utilizes Tumble Upon Impact (TUI) bullet technology which produces ballistic wound cavities that exceed the standards of both expanding and fragmenting bullets. The design of the TUI bullet causes the bullet to tumble down to 500 Feet Per Second (FPS). In confined areas and close quarter defense situations, the TUI bullet is also designed to lose momentum, so it is less likely to cause collateral harm to bystanders or structures. This powerful round provides exceptional accuracy, and is also reliable for hunting. This ammunition is new production, non-corrosive, boxer primed, in reloadable brass cases.

Please Note: This ammunition meets and follows SAAMI guidelines and standards.

  • I bought a box of this on a whim

    Posted by Ron Berger on Jul 15th 2020

    I had never shot this tumble ammo before and saw your company had it in stock and I bought a box. I have watched videos of people shooting it and was curious. I must say it is accurate and every round fired with no problems. I want to buy more to test it out. One box went way to fast. I will buy more when your company has it in stock. Thank you Ken for answering all my questions about this round. I know I kept you on the phone a long time. I thank all of you guys at munitions express for keeping all of us stocked with ammo during this crazy time.
