Ammo Inc stelTH 300 Blackout 220gr TMC Subsonic Ammo - 20 Rounds

The Ammo Inc stelTH 300 Blackout 220gr Total Metal Case ammunition delivers subsonic performance optimized for suppressed firearms. This heavy-grain load maintains velocity below the sound barrier while providing reliable cycling and consistent accuracy across multiple firearm platforms.

What Makes This Different

The stelTH line features Total Metal Case construction that eliminates lead exposure during handling and reduces barrel fouling compared to traditional lead-core bullets. The 220-grain projectile weight ensures subsonic velocities from most barrel lengths, making it ideal for suppressed applications where sound reduction takes priority. Clean-burning powder formulations minimize residue buildup and maintain consistent chamber pressures across temperature ranges.

Key Features

• 220-grain Total Metal Case bullets for reduced lead exposure and cleaner shooting
• Subsonic velocity profile optimized for suppressor use
• Consistent powder charges for reliable semi-automatic cycling
• Boxer-primed brass cases suitable for reloading
• Factory-fresh ammunition with rigorous quality control standards
• Compatible with AR-15 platforms and bolt-action rifles in 300 Blackout
• 20-round boxes packaged in 10-box cases for bulk purchases

This ammunition performs consistently in both direct impingement and piston-driven systems, maintaining reliable function while keeping noise signatures minimal. The heavy bullet weight provides excellent terminal performance at subsonic velocities, making it effective for hunting applications within appropriate ranges. Temperature stability ensures consistent performance from summer heat to winter cold, while the clean-burning powder formulation extends maintenance intervals.
