Product Description

Armscor 300BLK 147GR FMJ is a full metal jacket cartridge in .300 Blackout caliber designed for practice and training applications. The 147-grain projectile sits in the heavier weight class for this caliber, making it well-suited to subsonic velocities when paired with compatible barrel lengths.

This ammunition delivers the reliable feeding and consistent function shooters expect from FMJ loads. It works across a range of AR-15 platform firearms chambered in .300 Blackout, whether you’re running drills or zeroing optics.

Key Facts

• Bullet Weight: 147 Grain
• Product Code: Armscor-300BLK-147GR-20

What 147 Grain Means for 300 Blackout

The 147-grain weight typically performs at subsonic velocities in standard-length barrels. Subsonic loads reduce noise signature and work especially well when paired with suppressors. The heavier projectile retains energy better at close to mid-range distances compared to lighter, faster bullets.

FMJ construction means the lead core is encased in a copper jacket. This design reduces fouling in the barrel and feeds reliably through semi-automatic actions. Full metal jacket rounds are the standard choice for high-volume training because they cost less than expanding or barrier-blind projectiles.

Who This Ammunition Suits

.300 Blackout was developed to deliver .30-caliber performance in the AR-15 platform with only a barrel swap required. Shooters choose this caliber for its versatility across subsonic and supersonic loads, compact builds, and suppressor compatibility.

The 147-grain FMJ load works well for range practice, function testing, and zeroing your sights or optic. It is not designed for hunting or defensive use where controlled expansion matters. For a full selection of calibers and bullet weights, browse our ammunition inventory.

Frequently Asked Questions

Q: Is Armscor 300 Blackout 147 grain subsonic or supersonic?

A: The 147-grain bullet weight typically produces subsonic velocities in standard barrel lengths, though exact velocity depends on powder charge and barrel specs. Call 817-393-4000 to confirm performance details for your setup.

Q: What is the difference between 147 grain and lighter 300 Blackout loads?

A: Heavier bullets like 147 grain generally fly slower and work well for suppressed shooting, while lighter bullets in the 110 to 125 grain range achieve supersonic speeds and flatter trajectories. The choice depends on whether you prioritize noise reduction or downrange velocity.

Q: Can I use this FMJ ammunition for hunting?

A: FMJ bullets are not designed to expand on impact, so they are not recommended for hunting applications. Look for soft-point or hollow-point loads if you need terminal performance on game.

Q: Will this ammunition work in my suppressed 300 Blackout rifle?

A: The 147-grain weight class is commonly loaded to subsonic speeds, which pairs well with suppressors to reduce sound signature. Confirm your rifle’s barrel length and twist rate are compatible by calling 817-393-4000.

Q: How does Armscor ammunition compare to other brands?

A: Armscor is known for producing affordable, brass-cased ammunition that functions reliably in semi-automatic platforms. It sits in the training and practice category alongside other budget-friendly options, offering solid value for volume shooting.

Q: Do I need an FFL transfer to buy this ammunition in Texas?

A: Ammunition sales in Texas do not require an FFL transfer, though age and residency restrictions apply. Western Sport can process your order over the phone at 817-393-4000 or through our online shop.
