300 Blackout Ammo Reviews

Best Overall – Federal Premium American Eagle 150 Grain FMJ-BT

Specs

• Case: Brass

• Bullet Type: Full Metal Jacket Boat Tail

• Bullet Weight: 150 Grains

• Muzzle Velocity: 1,900 fps

• Muzzle Energy: 1,202 ft-lbs

Pros and Cons

Why I Chose It

Federal Premium consistently produces some of the best ammo on the market. Federal American Eagle 150 grain FMJ-BT is no exception. It’s accurate, reasonably priced, and reliable. I’ve purchased and fired Federal American Eagle many times and have rarely had a problem with it. It’s my go-to ammo to stock up on in bulk.

This ammo is ideal for a long day on the range because it’s very accurate (thanks to Federal’s uniform FMJ-BT bullets, brass cases, and powder charges) and reasonably priced. When I fire these rounds, I know I will get consistent performance out of them. They’re gonna fire, cycle, and hit where I’m aiming every time. I love that I get this consistency without breaking the bank.

However, I would prefer using a different bullet than the FMJ-BT bullet to put down a bad guy if I were forced to defend my family or myself. It doesn’t expand to inflict a wider wound channel as a self-defense and hunting bullet would have. That reduces its odds of instantly neutralizing the target. It also increases its odds of passing clean through said target, where it may jeopardize an innocent bystander.

Overall, Federal Premium American Eagle 150 grain FMJ-BT is the best 300 BLK ammo. It’s reliable, accurate, reasonably priced, and made by a trusted manufacturer. Don’t hesitate to make a bulk order today!

Best for Home Defense – SIG Sauer Elite Copper 120 Grain SCHP

Specs

• Case: Brass

• Bullet Type: Solid Copper Hollow Point (SCHP)

• Bullet Weight: 120 Grains

• Muzzle Velocity: 1,897 fps (6.75” Barrel)

• Muzzle Energy: 959 ft-lbs

Pros and Cons

Why I Chose It

The best 300 BLK ammo for home defense is SIG Elite Copper 120 grain solid copper hollow point (SCHP). It’s made by a trusted brand, accurate, and designed to perform best with short-barreled rifles in close quarters.

If I’m carrying a firearm for self-defense that’s not loaded with Hornady rounds, then it likely has SIG Elite loaded in its magazine. Many other shooters and I trust it to be accurate and pack a punch in defense situations.

The 120 grain SCHP bullet is designed to “retain weight through glass, drywall, and light auto sheet metal, making it ideal for tactical and defensive use,” according to SIG’s website. These rounds are designed for full power burn and velocity efficiency in barrels as short as 7”, making them ideal for home defense with an SBR.

Running an even shorter setup? We have a dedicated guide to the best 300 Blackout ammo for a 7.5” barrel.

My only frustration with these rounds is how expensive they are, but that’s normal for home defense ammo. It’s also not ridiculously overpriced compared to many other 300 BLK defense rounds.

SIG Elite 120 grain SCHP ammo is what you should load in your home defense 300 BLK mags. It’s accurate and reliable, and stops bad guys in their tracks.

Best Hunting Ammo – Barnes VOR-TX 120 Grain TAC-TX

Specs

• Case: Brass

• Bullet Type: TAC-TX (Polymer-Tipped Solid Copper)

• Bullet Weight: 120 Grains

• Muzzle Velocity: 2,100 fps (16” Barrel)

• Muzzle Energy: 1,175 ft-lbs

Pros and Cons

Why I Chose It

Barnes VOR-TX is trusted by countless hunters every hunting season because it’s reliable and packs enough punch to stop any deer.

While Barnes ammo is expensive, it does have high-quality, reliable materials and components to show for it. In this ammo’s case, that includes the TAC-TX bullet. The TAC-TX is exceptionally accurate thanks to its polymer tip. Its all-copper body gives it the fortitude requisite for deep penetration, which it makes all the deadlier via wide and energetic terminal expansion.

You can trust that Barnes VOR-TX 120 grain TAC-TX will perform when you have a trophy buck in your crosshairs. Grab some today!

Best Subsonic Rounds – Hornady Subsonic 190 Grain Sub-X

Specs

• Case: Brass

• Bullet Type: Sub-X (Subsonic – eXpanding)

• Bullet Weight: 190 Grains

• Muzzle Velocity: 1,050 fps (16” Barrel)

• Muzzle Energy: 465 ft-lbs

Pros and Cons

Why I Chose It

Hornady makes the list with their Subsonic 190 grain Sub-X ammo: designed for suppressed shooting by a trusted company. The subsonic Sub-X bullet’s long-range trajectory isn’t great. But in its defense, it isn’t intended to be.

The heavy 190 grain Sub-X is extra quiet when paired with a suppressor, and will still cycle through your AR. It is designed to reliably unleash terminal expansion at low velocities. It’s also plenty accurate within a subsonic 300 BLK cartridge’s conventional 100- to 150-yard effective range.

If you want the best subsonic ammo for your 300 BLK rifle, then you’ve got to check out how well Hornady Subsonic 190 grain Sub-X treats your suppressor.
