300 Blackout Ammo

300 Blackout Ammo for Sale

The current Steinel 300 Blackout selection includes two subsonic loads:

– 300 Blackout 200gr Subsonic SCHP
The 200gr Subsonic SCHP uses a 200-grain solid copper hollow point projectile. It provides a lead-free option for shooters who specifically want a solid copper bullet in a subsonic .300 Blackout load.

– 300 Blackout 220gr Subsonic TMJ
The 220gr Subsonic TMJ uses a 220-grain full metal jacket-style projectile. The heavier bullet is suited to the subsonic side of the .300 Blackout’s design.

What Is .300 Blackout?

The .300 Blackout is a centerfire rifle cartridge that uses a .308-inch-class bullet. It was developed to give the AR-15 platform a .30-caliber option while retaining the compact characteristics of the platform.

The cartridge is particularly notable for its flexibility. It can be loaded with relatively light bullets at supersonic velocities or much heavier bullets at subsonic velocities.

That means two .300 Blackout loads can behave very differently even though they use the same cartridge.

Subsonic vs. Supersonic 300 Blackout Ammo

Choosing between subsonic and supersonic ammunition largely comes down to the intended application.

– Subsonic 300 Blackout ammo is loaded below the speed of sound. It is commonly used with suppressors because keeping the projectile below the speed of sound eliminates the projectile’s supersonic crack.

– Supersonic 300 Blackout ammo travels faster than the speed of sound and generally provides higher velocity and a flatter trajectory than subsonic ammunition.

Neither is simply a replacement for the other. The appropriate load depends on the firearm, barrel, intended use, and, where applicable, suppressor setup.

300 Blackout Subsonic Ammo for Sale

Subsonic ammunition is one of the features that distinguishes the .300 Blackout from many other common rifle cartridges.

Heavy bullets are commonly used to keep .300 Blackout projectiles below the speed of sound while maintaining useful bullet mass. For comparison, SAAMI’s current centerfire rifle standards include a 220-grain .300 AAC Blackout proof-cartridge reference.

Steinel’s subsonic selection includes both 200gr SCHP and 220gr TMJ loads, giving shooters two different projectile designs and weights to consider.

How to Choose 300 Blackout Ammo

Start with the firearm and the intended application.

For suppressed shooting, subsonic ammunition is the obvious place to start. Make sure the ammunition’s velocity is appropriate for the intended setup.

For hunting, choose a projectile designed for the game being hunted rather than selecting ammunition based only on bullet weight.

For range shooting, consider accuracy, reliability, bullet type, and cost.

Barrel length and twist rate are also worth checking, particularly when comparing different bullet weights.

Why Buy 300 Blackout Ammo from Steinel Ammunition Co.?

Steinel Ammunition Co. produces 300 Blackout ammo in different configurations, including heavy subsonic loads.

The current selection includes a 200gr Subsonic SCHP and a 220gr Subsonic TMJ, giving shooters a choice between two different bullet designs.

The individual product pages provide the relevant load information so that customers can choose ammunition based on their firearm and intended application.

Storage and Handling

Store ammunition in a cool, dry location away from excessive heat and moisture. Keeping ammunition in its original packaging also helps maintain identification and lot information.

Before loading, confirm that the cartridge marking on the ammunition matches the caliber marked on the firearm.

300 Blackout and Short-Barrel Firearms

The .300 Blackout was designed with compact firearm configurations in mind, which is one reason it is commonly found in rifles and other platforms with shorter barrels.

Barrel length has a direct effect on velocity. The same ammunition can produce different results when fired from different barrel lengths, so published ballistic figures should always be considered in relation to the barrel used for testing.

300 Blackout vs. 5.56 NATO

Both cartridges are commonly associated with the AR-15 platform, but they are not interchangeable.

The 5.56 NATO uses a .224-inch-class bullet, while the .300 Blackout uses a .308-inch-class bullet. Their barrels, cartridges, and ammunition specifications are different.

A .300 Blackout firearm must use .300 Blackout ammunition, and a 5.56 firearm must use ammunition appropriate for its chambering.

It is particularly important to keep these cartridges separated because .300 Blackout ammunition can physically fit into some 5.56/.223 magazines, creating a potentially dangerous ammunition mix-up. Firearm manufacturers warn users to verify the cartridge before loading.

Compatible Firearms for 300 Blackout

The .300 Blackout is used in a variety of firearms specifically chambered for the cartridge, including:
– AR-15-style rifles
– SIG Sauer MCX
– SIG Sauer MCX Rattler

Rifles styled like the AR-15 come in many sizes and have many options, depending on the manufacturer. The lower receiver, without the receiver extension, rear takedown pin, and buttstock, is shown at bottom.

SIG Sauer, for example, lists the MCX and MCX Rattler in .300 Blackout.

300 Blackout vs. .308 Winchester

The .308 Winchester is a larger, higher-powered rifle cartridge than the .300 Blackout and is generally better suited to applications requiring greater velocity and longer-range performance.

The .300 Blackout has a different purpose. Its strengths include heavy bullets, subsonic loads, and compatibility with compact platforms.

The two cartridges use different cases and are not interchangeable.

Frequently Asked Questions

Q1. What is 300 Blackout ammo good for?
300 Blackout ammunition is commonly used for range shooting, hunting where legal, and both subsonic and supersonic applications.

Q3. Where can I buy 300 Blackout subsonic ammo?
Steinel Ammunition Co. offers 300 Blackout subsonic ammo for sale, including 200gr SCHP and 220gr TMJ loads.

Q4. Will 300 Blackout stop a bear?
The .300 Blackout can be used for black bear with an appropriate supersonic hunting load and proper shot placement. Published testing has shown suitable .300 Blackout hunting loads can provide adequate penetration and expansion on black bear.

Q5. What hits harder, .308 or 300 Blackout?
.308 Winchester generally hits harder. It typically produces substantially higher velocity and muzzle energy, while .300 Blackout is designed around heavier bullets, shorter barrels, and subsonic or supersonic loads.

Q6. What’s so special about 300 Blackout bullets?
The .300 Blackout can use a wide range of bullet weights, including heavy bullets for subsonic loads and lighter bullets for supersonic loads. This gives the cartridge flexibility for different shooting applications.

Q7. Why is 300 Blackout so expensive?
.300 Blackout ammunition can cost more because it is produced in smaller volumes than very common cartridges and many loads use heavier or specialized projectiles. Current retail pricing also varies considerably by bullet type and application.

Q8. Do Navy SEALs use 300 Blackout?
.300 Blackout has been used by U.S. special operations forces, but publicly available information does not establish that every Navy SEAL unit uses it. The cartridge has been associated with specialized suppressed and short-barrel platforms.

Q9. Will 300 Blackout over penetrate?
Overpenetration depends on the bullet construction, velocity, target, and what is behind the target. No .300 Blackout load can be considered automatically resistant to overpenetration.

Q10. Is 300 Blackout overkill for deer?
Generally, no. The .300 Blackout is used for deer with appropriate hunting ammunition, particularly at closer distances. It is, however, important to select a bullet designed for deer and use the cartridge within its practical range.
