Fiocchi Range Dynamics 9mm Subsonic Ammo - 158 Grain FMJ

Heavy Subsonic 9mm Ammo

This is Fiocchi's 9mm Luger practice load built around a heavy 158 grain full metal jacket bullet at a rated 850 feet per second. That speed keeps the round subsonic, meaning slower than the speed of sound, so it avoids the sharp crack a faster bullet makes in flight. It suits range sessions where you want a softer, slower-pushing recoil impulse, and shooters running a suppressor on a 9mm host.

Features

• 9mm Luger Chambering — Also called 9x19mm, this is the cartridge used by most modern full-size and compact semi-automatic pistols.
• 158 Grain Bullet — At roughly 10.2 grams, it sits at the heavy end of 9mm weights, well above the common 115 and 124 grain loads.
• Full Metal Jacket — A copper jacket wraps the bullet nose, which helps it feed smoothly and keeps lead off your hands and out of the bore.
• Subsonic 850 FPS — The box lists a velocity of 850 feet per second, under the roughly 1,100 fps threshold where a bullet breaks the sound barrier.
• Suppressor-Friendly Load — Because the bullet stays subsonic, a suppressor only has to quiet the muzzle blast and not a supersonic crack as well.
• Brass Cases — The cartridges use brass casings, the standard material for centerfire handgun ammunition.
• Centerfire Priming — The primer sits in the center of the case head, as required by 9mm pistols.
• 50 Rounds Per Box — Each box holds 50 cartridges, enough for a few magazines' worth of drills or a focused practice session.

Load and Packaging

The box carries Fiocchi's Pistol Shooting Dynamics branding and the product code 9APE, with the caliber, bullet weight, FMJ type and 850 fps velocity printed on the end flap for quick identification on the shelf. The rounds show a copper-jacketed bullet seated in a brass case. Heavy subsonic 9mm cycles differently from lighter loads, so confirm your pistol runs it reliably before relying on it in a match or a suppressed setup.
