Maxim 300blk Sbsnc 190gr Tui Sb Blem

The Maxim 300blk Sbsnc 190gr Tui Sb Blem represents a purpose-built subsonic cartridge engineered for short-barreled rifle platforms and suppressed fire applications. Manufactured by Maxim Defense Industries, this 300 Blackout ammunition delivers reliable performance in tactical operations where noise signature reduction is critical—whether for law enforcement dynamic entries, military close-quarters operations, or precision suppressed shooting. The subsonic load ensures supersonic crack is eliminated when paired with a quality suppressor, maintaining the stealth advantage operators demand in high-threat environments.

Each round features a 190-grain solid copper projectile engineered with Tumble Upon Impact (TUI) design geometry, which induces controlled tumbling upon target contact for enhanced terminal ballistics and energy transfer. The subsonic velocity profile prevents bullet destabilization at transonic speeds—a common failure point in subsonic ammunition—ensuring consistent accuracy and predictable terminal performance at 25 to 100 yards. Maxim's quality control and precision loading provide the shot-to-shot consistency operators require when every round counts, making this ammunition suitable for both suppressed 8-inch and 10-inch short-barrel configurations.

Tactical professionals, specialized law enforcement units, and military end-users running 300 Blackout SBRs will find this cartridge ideal for suppressed precision work where subsonic velocities eliminate the need for hearing protection in non-fire environments. The 20-round box configuration allows for magazine-compatible carry and deployment, with bulk case quantities available for training cycles and extended operations. This blemished-box offering provides substantial savings while maintaining full functional integrity—the external packaging damage does not affect ammunition quality or performance. Compatible with all standard 300 Blackout chambers; verify suppressor compatibility for optimal sound signature reduction.
