Armscor .300 Blackout 147-grain FMJ ammunition delivers reliable, affordable rounds for shooters working with subsonic loads. Whether you're running suppressed rifles, training at distance, or stocking up for range sessions, this .300 Blackout ammunition offers consistent performance at a competitive price point. Armscor, an ISO 9001 certified manufacturer based in the Philippines, has built a reputation for dependable ammunition used by police, military, and civilian shooters worldwide.
The 147-grain full metal jacket bullet is purpose-built for the .300 Blackout cartridge, leaving the muzzle at 1800 fps with 1060 ft-lbs of energy. This subsonic velocity profile makes it especially well-suited to suppressed shooting, where the round stays subsonic throughout its flight path even at extended distances. Whether you're zeroing a new setup, running drills, or shooting steel downrange, this ammunition maintains predictable energy retention—still delivering 580 ft-lbs at 300 yards.
Available in convenient 20-round boxes for immediate needs or bulk 200-round cases for shooters who run serious volume. Armscor's commitment to SAAMI and CIP compliance ensures safe, consistent chamber fit and performance across properly headspaced .300 Blackout rifles.

Frequently Asked Questions
Is this ammunition subsonic?
Yes. The 147-grain load launches at 1800 fps from the muzzle and maintains subsonic velocity (below 1125 fps) throughout its flight path, making it well-suited for suppressed rifles.
What's the difference between the 20-round box and bulk 200-round case?
Both contain the same ammunition with identical ballistics. The 20-round box is ideal for shooters trying a load or keeping manageable quantities on hand. The 200-round bulk case is better for high-volume shooters and range sessions where you'll benefit from the cost efficiency of buying in larger quantities.
Can I use this in my .300 Blackout rifle?
This ammunition is manufactured to SAAMI and CIP specifications for safe use in properly headspaced .300 Blackout rifles. Always verify your firearm's chambering and consult your rifle's manual before firing any ammunition.
What are common uses for this load?
The 147-grain FMJ load is well-suited for target practice, range shooting, plinking, and training—especially from suppressed .300 Blackout rifles where the subsonic velocity is a significant advantage.
