Ammunition Load
The ammunition load specifies the brand and specific projectile design used in the factory cartridge. The chart separates supersonic ammunition from subsonic ammunition. Supersonic loads feature lighter bullets designed for rapid expansion and maximum kinetic energy transfer. Subsonic loads feature heavy projectiles specifically engineered to stay below the speed of sound, eliminating the loud sonic crack for suppressed shooting.
Bullet Weight
Bullet weight is measured in grains. For this caliber, weights typically range from 110 grains up to 220 grains. The lighter 110 grain to 125 grain options provide the fastest velocities and flattest trajectories, making them ideal for hunting thin skinned game. The heavy 190 grain to 220 grain bullets are used almost exclusively for subsonic suppressed fire, relying on mass rather than speed to maintain downrange energy.
Distance
Distance is measured in yards from the muzzle of the firearm. The data covers performance from the muzzle out to 500 yards. This provides a complete picture of the effective range for both supersonic loads intended for medium range engagements and subsonic loads intended for close quarters.
Velocity
Velocity indicates the speed of the projectile measured in feet per second. Supersonic loads generally launch between 2,200 and 2,400 feet per second from a standard 16 inch barrel. Subsonic loads intentionally launch around 1,000 to 1,050 feet per second to ensure they remain below the speed of sound, which is roughly 1,125 feet per second at sea level.
Energy
Energy measures the kinetic knockdown power of the bullet, calculated in foot pounds. Supersonic loads generate approximately 1,350 foot pounds of energy at the muzzle, which is highly comparable to the classic 7.62x39mm Russian cartridge. Subsonic loads generate much less energy, typically around 450 to 500 foot pounds, making shot placement critical for ethical hunting.
Bullet Drop
Bullet drop shows the physical height of the bullet relative to the line of sight. In this chart, supersonic loads are calculated using a standard 100 yard zero, meaning the bullet intersects the crosshairs exactly at 100 yards. Subsonic loads are calculated using a 50 yard zero, which is the industry standard for low velocity suppressed weapon systems. The negative 1.5 inch measurement at the muzzle accounts for the standard height of an AR-15 optic above the bore.
Cartridge Overview
Developed in 2009 by Advanced Armament Corporation, this cartridge was created to provide a specialized short range powerhouse for the AR-15 platform. The military needed a round that delivered more energy than standard 5.56 NATO while using the exact same magazines, standard bolt face, and standard lower receiver. Engineers accomplished this by shortening a .223 Remington case and necking it up to accept a .308 caliber bullet. The result is an incredibly versatile cartridge that requires only a barrel swap to function perfectly in any standard AR-15.
Supersonic Performance
When loaded with light bullets in the 110 grain to 125 grain class, this round behaves like a modern lever action brush gun. It excels in dense woods and close quarters where heavy hitting kinetic energy is required. The supersonic loads deliver massive terminal performance and excellent barrier penetration capabilities compared to smaller caliber options.
Subsonic Capabilities
The true genius of this cartridge lies in its subsonic performance. Because the case volume is relatively small, it burns powder highly efficiently. When paired with heavy 220 grain bullets and fired through a quality silencer, it produces an incredibly soft report with virtually zero muzzle flash. This makes it a premier choice for tactical teams, home defense scenarios, and feral hog eradication at night.
Hunting Performance
For hunters, proper ammunition selection is everything. Supersonic expanding bullets like the Barnes TAC TX or Hornady VMAX are devastating on whitetail deer and feral hogs. They provide excellent tissue destruction and deep penetration on medium game. Conversely, hunters must be highly cautious when hunting with subsonic ammunition. Most heavy match bullets will not expand at 1,000 feet per second, acting more like a pistol caliber through the animal.
Effective Range
The effective range heavily depends on the ammunition used. A quality 110 grain supersonic load retains enough energy and velocity to ethically harvest a deer out to approximately 200 yards. Beyond 250 yards, the steep trajectory curve makes hit probability difficult on small targets. Subsonic loads have a much shorter practical effective range, generally limited to 75 yards or less for hunting purposes due to the massive arc in bullet drop.
Frequently Asked Questions
Can I use 5.56 NATO magazines with this ammunition?
Yes. The entire cartridge was reverse engineered to feed perfectly from standard AR-15 magazines without any modification to the follower or feed lips. You retain full 30 round capacity.
Does a shorter barrel ruin the ballistics?
No. This cartridge uses very fast burning powder. It achieves complete powder burn in approximately 9 inches of barrel length. Firing it from a 9 inch barrel only costs roughly 100 to 150 feet per second compared to a 16 inch barrel, making it the ultimate choice for short barreled rifles.
Will firing standard ammunition through a suppressor damage it?
You can safely fire both supersonic and subsonic ammunition through most high quality .30 caliber centerfire suppressors. However, supersonic ammunition will still produce a loud sonic crack downrange, whereas subsonic ammunition will completely eliminate the sonic boom.
