.300 Blackout Overview
The .300 AAC Blackout (7.62x35mm) represents a revolutionary approach to AR-platform versatility. Developed by Advanced Armament Corporation in 2011, this cartridge was engineered to provide both supersonic and subsonic capability while maintaining full compatibility with standard AR-15 magazines and bolts. It delivers .30 caliber power from an AR-15 platform with only a barrel change.
The cartridge's dual-purpose nature makes it uniquely versatile. In its supersonic form, it roughly matches the ballistics of the 7.62x39mm, making it effective for hunting and tactical applications out to 300 yards. In its subsonic configuration, it offers exceptional suppressed performance while maintaining accuracy and terminal effectiveness. This flexibility has made it increasingly popular among hunters, competitive shooters, and defensive users who appreciate its adaptability and AR-15 compatibility.
Advantages and Disadvantages
Pros
- Functions both supersonically and subsonically
- Compatible with standard AR-15 magazines and bolts
- Excellent suppressed performance
- Superior terminal performance compared to 5.56 NATO
- Minimal modification needed to convert 5.56 AR-15
Cons
- More expensive than 5.56 NATO ammunition
- Limited effective range compared to 5.56 NATO
- Significant trajectory difference between super/subsonic loads
- Less readily available than common rifle cartridges
- Requires careful attention to load selection for intended use
.300 Blackout Ballistics
The .300 Blackout achieves velocities of 1,800-2,400 fps with supersonic 110-150 grain bullets, while subsonic loads typically drive 220-grain bullets at 900-1,000 fps. Supersonic loads generate between 1,300-1,400 ft-lbs of muzzle energy from 16-inch barrels, with subsonic loads producing around 500 ft-lbs. The trajectory below is for supersonic, use our trajectory calculator to customize ballistic data for whatever load you are using.

What .300 Blackout Does Best
The .300 Blackout's versatility allows it to excel in multiple roles, though its primary strengths lie in its ability to serve as both a supersonic hunting/defensive round and a superior subsonic suppressed option. This dual-purpose nature, combined with AR-15 compatibility, makes it uniquely capable in several key applications.
Suppressed Shooting
- Exceptional performance with subsonic loads and a suppressor, offering superior sound reduction while maintaining accuracy and terminal effectiveness
Hunting
- Effective on medium game out to 300 yards with supersonic loads, while subsonic loads work well for closer range hunting where noise reduction is valuable
Home Defense
- Supersonic loads offer improved terminal performance over 5.56 NATO, while subsonic loads minimize overpenetration risks and protect hearing when suppressed
Types of Projectiles
Full Metal Jacket (FMJ)
- Training, target practice, and general range use in both super and subsonic configurations
Open Tip Match (OTM)
- Maximum accuracy for precision shooting and competition use
Expanding Hollow Point
- Hunting and defensive use, optimized for reliable expansion at both super and subsonic velocities
Ballistic Tip
- Controlled expansion for hunting applications, particularly with supersonic loads
Common .300 Blackout Bullet Weights
110-125 grain
- Supersonic loads optimized for maximum velocity and flatter trajectory
150-168 grain
- Medium-weight loads balancing velocity and energy transfer
190-220 grain
- Subsonic loads designed for suppressed use and maximum terminal effect
