Description
Winchester Super 300 BLK 200gr ammunition from Winchester (Super Suppressed) loads a 200 grain Open Tip Range in 300 AAC Blackout. Each box holds 20 rounds.
Built for Subsonic Shooting
This load pairs a heavy 200 grain Open Tip Range with the 300 AAC Blackout at subsonic velocity, a combination popular with shooters running suppressed rifles.
Keeping the bullet below the speed of sound removes the supersonic crack, so a suppressed rifle sounds much quieter with Winchester Super 300 BLK 200gr than with supersonic ammunition. Without a suppressor the report is still loud, so always wear hearing protection.
Subsonic loads drop faster and carry less energy than supersonic loads, so they are best suited to shorter ranges. Confirm your zero and know your holdovers before you rely on this load.

Subsonic Shooting Tips
Use Winchester Super 300 BLK 200gr only in firearms chambered for 300 AAC Blackout.
Some semi-automatic rifles need a suppressor or an adjustable gas system to cycle subsonic ammunition reliably; test it in your rifle first.
Check that your barrel twist stabilizes this bullet weight.
Suppressor ownership requires federal approval and is not legal in every state; check your local laws.
Winchester Super 300 BLK 200gr is a quiet choice for shooters who want a ready-made subsonic ammo from a known maker.
Different zero
A subsonic load usually prints well below a supersonic load at the same zero. Many shooters keep a separate zero or a written holdover chart for subsonic ammunition.
Short-range energy
Heavy subsonic bullets are built to expand or tumble at low velocity, but they still lose energy quickly. Keep shots close and pick the right job for this load.
Hearing protection
Even suppressed, gunfire is loud. Wear hearing protection whenever you shoot.
Reading the box
The box lists the caliber, bullet weight and bullet type. Always match the cartridge to the caliber stamped on your firearm’s barrel or slide, and never fire ammunition that is not specified for your firearm.
About Winchester
Winchester Super 300 BLK 200gr comes from Winchester, and the specifications listed here follow the maker’s and our distributor’s published data for this item. Compare loads by bullet weight, bullet type and intended use to find the best fit for your firearm.
Buying the right amount
When you find a load that performs well, buy enough for practice and the full season at once. Ammunition from the same lot tends to perform the same, which keeps your results consistent.
Safety first
Always treat every firearm as loaded, keep the muzzle pointed in a safe direction and keep your finger off the trigger until you are ready to shoot. Wear eye and ear protection every time you shoot.
Understanding bullet weight
Heavier bullets in a given caliber usually leave the muzzle slower but carry momentum well and resist wind drift, while lighter bullets shoot faster and flatter at shorter ranges. Neither is better in every case; the right choice depends on the game, the distance and your firearm.
Choosing the right load
Start with the job you need the ammunition to do, whether that is hunting, target shooting or practice. Then match the load to that job, and finally test a few boxes in your own firearm, because every barrel has its preferences.
