The Ellier & Bellot Blackout Subsonic 200 is a precision-engineered, full-metal-jacket rifle cartridge designed for reliable subsonic performance. This premium .300 AAC Blackout (300 BLK) round features a heavy 200‑grain bullet, optimized for quiet, controlled shooting—especially when paired with a suppressor or used in training environments.
At its core, the Sellier & Bellot Blackout Subsonic 200 combines a dense lead core with a durable copper-zinc jacket (CuZn 10), allowing for stable flight characteristics, minimal barrel fouling, and consistent feeding in compatible platforms. According to manufacturer specifications, the bullet travels at approximately 323 m/s (1,060 fps) from a 16-inch test barrel, producing around 678 joules of muzzle energy.
Mechanically, this ammo operates by using smokeless powder under carefully controlled loads to remain below the speed of sound. That ensures suppressed use remains whisper‑quiet, reducing both muzzle report and recoil. Because it’s a full metal jacket (FMJ) round, it’s built for consistent target shooting, training, and match use—rather than expansion or defensive penetration.
How It Works & Chemical Composition
-
Bullet Composition: Lead core, CuZn 10 jacket—the standard combination for FMJ rounds.
-
Case: Factory‑new brass, non-corrosive and reloadable for economically minded shooters.
-
Primer: Boxer-primed, offering reliable ignition and compatibility with standard reloading practices.
-
Propellant: Smokeless powder, carefully calibrated to produce subsonic velocities without sacrificing consistency or safety.
When fired, the powder charge propels the heavy bullet smoothly yet slowly (relative to supersonic rounds), keeping pressure moderate and noise subdued. The FMJ profile ensures a streamlined shape and dependable cycling in semi-auto rifles, while the brass case supports reloading.
Benefits & Advantages
-
Low Noise Signature: The subsonic velocity helps to significantly reduce the sound of the shot, particularly when used with a suppressor or in enclosed ranges.
-
Stable Performance: The 200-grain weight offers excellent stability, reducing flyer risk and improving shot-to-shot consistency.
-
Cost‑Effective Training: Ideal for range shooting and training sessions thanks to its FMJ design and reloadable brass case.
-
Long-Term Storage: Because it’s non-corrosive and factory new, it stores well over time without degradation.
-
Reloadable: For shooters who reload, the brass cases provide an economical solution for repeated use.
Safety & Handling
Safety is paramount with any ammunition. Users should:
-
Store the cartridges in a cool, dry place to avoid corrosion or primer degradation.
-
Follow standard firearm safety protocols: always treat every round as live.
-
Use within firearm systems rated for .300 AAC Blackout.
-
When shooting suppressed, ensure the suppressor is properly attached and maintained.
-
Clean the barrel regularly—heavy FMJ bullets and lead cores can contribute to fouling over time.
Longevity & Usage Scenarios
The Ellier & Bellot Blackout Subsonic 200 is built for durability and longevity. Its brass casing and non‑corrosive primer make it well suited for long-term storage. Because it is reloadable, you can maximize each round’s potential over multiple uses, reducing cost per shot.
Common usage scenarios include:
-
Range Training: As target practice or for developing marksmanship fundamentals.
-
Suppressed Shooting: Designed to perform reliably when used with a suppressor, thanks to its subsonic profile.
