Winchester Ammunition, Super Suppressed, 300 BO, 200 Gr, (20 Round)

Winchester Super Suppressed — 300 Blackout, 200 gr Open-Tip — 20-Round Box

Suppressed-ready performance. Heavy-for-caliber projectile for quiet, controllable shooting.

The Winchester Super Suppressed 300 Blackout 200-grain Open-Tip (OT) load is a range- and suppression-focused cartridge packaged in a compact 20-round box. Built around a heavy 200-grain projectile and Winchester’s Super Suppressed line engineering, it’s intended for reliable feeding and tuned performance in AR-style pistols and rifles set up for 300 Blackout—especially when used with a sound moderator and appropriate subsonic ammunition practices.

Key Features

• Caliber / Load: 300 Blackout — 200 grain Open-Tip projectile.

• Quantity / Packaging: 20 rounds per box — compact, ready-for-duty or range use.

• Bullet Type: Open-tip (OT/OTM) design for stable flight and controlled terminal characteristics.

• Intended Use: Formulated for suppressed shooting and subsonic-favoring setups.

• Case: Brass case construction for reliable extraction and potential reloading where permitted.

• Components: Factory-match components for consistent ignition and function (Winchester quality control).

• Feeding: Designed for reliable feeding in common 300 Blackout magazines and platforms.

Why It Stands Out

Winchester’s Super Suppressed line focuses on minimizing report and delivering consistent, usable performance when paired with a moderator. The heavy 200-grain projectile helps keep velocities in the subsonic band in many setups, improving suppression effectiveness while offering predictable feeding and terminal behavior for defensive or specialized range work.

Perfect For

• Shooters running suppressed 300 Blackout rifles or pistol-caliber ARs

• Hunters and tactical shooters who use heavy-bullet suppressed loads

• Instructors and trainers teaching suppressed-fire fundamentals and subsonic ballistics

• Range regulars who prefer brass-cased, factory-built suppressed loads
