Magtech 300 Blackout 200gr Subsonic FMJ Tactical Training Ammo - 50 Rounds

Whether you're running suppressed drills or stacking training rounds downrange, Magtech 300 Blackout 200gr subsonic FMJ ammunition delivers reliable, affordable performance without the supersonic crack. Built for shooters who want to maximize trigger time on their 300 Blackout rifle setups—especially those running a can—this tactical training ammo keeps velocity subsonic while maintaining consistent, predictable ballistics. The 200-grain full metal jacket bullet is heavy-for-caliber by design, giving you the ballistic characteristics suppressed .300 BLK shooters actually want.

Magtech has built a reputation for no-nonsense, budget-conscious ammo that doesn't sacrifice reliability. This 50-round box fits the same ethos: you get honest ammunition loaded to subsonic velocities, ready to run through your rifle without drama. The FMJ construction is straightforward—it's designed for function and training, not barrier-blind performance—so you can focus on putting rounds downrange and honing your fundamentals.

Running a suppressor? This load was built with that setup in mind. The subsonic velocity keeps your sound signature low and your action cycling smooth without the supersonic overexpressure that can rattle suppressors and waste energy. Pick up a box (or several) and get the training volume you need without breaking the bank or your hearing protection.

Frequently Asked Questions

Is this ammo good for suppressed rifles?

Yes. This round is loaded subsonic specifically for suppressed .300 Blackout rifles. The 200-grain bullet and 1,017 fps velocity keep the shot below the sound barrier, which is exactly what you want when running a can.

What's the difference between subsonic and standard .300 Blackout?

Subsonic .300 BLK stays below the speed of sound (roughly 1,125 fps at sea level), keeping shots quieter, especially when suppressed. Standard loads go supersonic and produce an audible crack. This load is subsonic, so it plays nice with your suppressor.

Can I use this in any .300 Blackout rifle?

Yes, this ammunition is compatible with any rifle chambered in .300 Blackout. However, subsonic loads may not cycle reliably in all piston-driven or short-stroke systems; semi-auto function depends on your rifle's design and gas system.

Is this FMJ round good for training only, or can I hunt with it?

FMJ construction makes this round best suited for training and range work. For hunting, you'll want ammunition designed with controlled expansion.
