Official-data note: Scorpion Ammo publishes muzzle velocity and energy for SKU 300B220-SUB20 but does not publish BC or a downrange factory table. No estimated BC is presented as manufacturer data.

Manufacturer: Scorpion Ammo. Exact official product pages and technical documents are recorded in the editorial verification log. Any retailer-listed field is labeled.

Ballistics Table

Official Scorpion Ammo muzzle figures. Downrange velocity, energy, drop, and 10 mph wind drift are not published for this exact load.

Key takeaway: The verified factory figures establish this as a 220 gr subsonic load. Chronograph the ammunition in the actual firearm before building a firing solution because barrel length, suppressor configuration, temperature, and lot can change measured velocity.

Why This Load Exists

Subsonic 300 Blackout ammunition occupies a purpose-built niche that no other mainstream cartridge fills as efficiently. The 300 BLK cartridge was engineered from the ground up to cycle reliably in AR-15 platforms with both supersonic and subsonic loads using the same bolt and magazine, requiring only a barrel swap from 5.56 NATO. The 220 gr subsonic variant specifically targets the suppressor market: by keeping the projectile below approximately 1,125 fps (the speed of sound at sea level, standard conditions), the supersonic crack — the ballistic shockwave that accounts for a significant portion of unsuppressed gunshot noise — is eliminated entirely.

The 220 gr bullet weight is not arbitrary. Heavier projectiles in the subsonic window carry more momentum and energy than lighter subsonic bullets, partially compensating for the velocity reduction. At 549 ft-lbs, this load delivers meaningful terminal energy within practical ranges while staying comfortably below the sound barrier. Scorpion Ammo’s entry into this segment reflects sustained market demand from suppressor owners, tactical operators, and precision shooters who prioritize hearing protection and noise discipline without transitioning to a dedicated pistol-caliber carbine.

Best Uses

Good fit:

• Suppressed AR-15 or AR-pistol platforms chambered in 300 Blackout where hearing protection and noise minimization are priorities
• Indoor or noise-sensitive range environments where supersonic crack would be disruptive or prohibited
• Short-range precision work inside 150 yards where the subsonic trajectory is manageable
• Function and point-of-impact testing in the actual host before relying on the load for any specialized application
• Training and practice with a suppressor-equipped host where extended sessions benefit from reduced noise exposure

Not the right tool for:

• Long-range shooting beyond 200 yards, where the steep subsonic trajectory drop makes precise engagement significantly more difficult
• Unsuppressed use where the velocity reduction compared to supersonic 300 BLK loads offers no practical benefit
• Hunting large or dangerous game where higher terminal energy and deeper penetration from faster loads are more appropriate
• Semi-automatic cycling reliability in all gas systems — short-barreled or improperly tuned gas systems may not cycle reliably with subsonic loads; always verify function in your specific platform
• Applications where supersonic terminal performance is required, such as longer-range varmint or predator hunting

Reliability Notes

No structured submissions yet.

Based on the manufacturer product description and general open-source information about this load category: Scorpion Ammo claims this load delivers reliable subsonic performance at 1,060 fps with consistent cycling in 300 Blackout-chambered AR platforms. No independent, structured reliability testing data is currently available for this specific load from this manufacturer.

It is worth noting — from open sources and general 300 Blackout subsonic knowledge — that subsonic loads in semi-automatic platforms are more sensitive to gas system tuning than supersonic loads. Shooters using pistol-length or carbine-length gas systems, or adjustable gas blocks, should verify reliable cycling before field use. This is a platform-specific consideration, not necessarily a reflection of this ammunition’s quality. All notes here reflect manufacturer claims or open-source category knowledge, not structured test data.
