300 Blackout Supersonic Ammo | Fenix Ammo

300 blackout supersonic ammo is the loud half of the caliber's split personality, and it is where the cartridge earns its keep in daylight. Fenix loads a 110 grain FXP VMAX that hunters pick for its expanding polymer tip, and a 150 grain FMJ in a 250 round pack that handles the volume training. Both run full speed at their published velocities, both ship factory direct from Michigan with live pricing below.

300 Blackout Supersonic Ammo, Explained

Run supersonic and the .300 Blackout behaves like the short barrel thumper it was designed to be, carrying real energy through the distances an AR pistol or SBR actually works at. The crack is back, of course, so this is the lane for unsuppressed range days and field use rather than whisper quiet sessions. Published velocities on each product page show exactly what full speed means per load. If your Blackout also wears a can for quiet work, keep this page and the subsonic page bookmarked as a pair; most owners shop both.

Choosing Between 110 VMAX and 150 FMJ

The 110 grain FXP VMAX is the specialist: lighter, faster, wearing an expanding polymer tipped projectile that hunters favor, and packed 100 to a bag. The 150 grain FMJ is the generalist, a non expanding trainer in the caliber's only 250 count pack. Buy the FMJ for skills, the VMAX for the job, and let each do what it is built for. Both come factory direct from our Michigan facility with live pricing on their cards, so equipping both roles is one order, not a hunt.

Frequently Asked Questions

Which supersonic load should I hunt with?

The 110 grain FXP VMAX is the expanding option of the pair, which is what field use calls for. Confirm your local regulations on caliber and projectile before the season starts.

Is the 150 grain FMJ good for training?

It is the training load of the whole caliber: full speed, non expanding, and the only Blackout load we pack 250 to a bag, which makes it the value pick for volume.

Can I shoot supersonic ammo through my suppressor?

Mechanically yes, and many do; you keep the muzzle blast reduction but the supersonic crack remains. For true quiet, that is what our subsonic loads are for.
