Fiocchi 5.7x28mm: Range Dynamics Subsonic

The 5.7x28mm cartridge was designed for optimized use through PDWs and handguns, and as a direct competitor with the 9mm. It’s a cartridge made to perform in dynamic situations and one often run suppressed, so it comes as no surprise Fiocchi offers Range Dynamics Subsonic in 5.7x28mm. This load is fantastic for training use whether your gun is suppressed or not. If you’re serious about self-defense training with your 5.7x28mm, this is a load worth a closer look.

According to Fiocchi, Range Dynamics Subsonic 5.7x28mm 62-grain FMJ is ideal for either high-volume suppressed shooting or simply training unsuppressed at the range. As full metal jacket rounds this ammunition is specifically meant for training purposes, and because it’s subsonic, it’s meant to reduce decibel levels, too. And if you’re shooting for fun at paper or steel targets, this ammunition is great for that as well.

If you’re using your 5.7x28mm for defensive purposes, whether home defense or self-defense out and about, you should spend time training. Honing your handgun and/or PDW skills is a must when you could end up relying on those skills to save your life or the life of a loved one. Utilizing ammunition like Fiocchi Range Dynamics Subsonic 5.7x28mm 62-grain FMJ for skill-related trigger time is a good idea because it both makes it more affordable and, if you have a suppressor, means it’s quieter. Protecting your hearing should always be a top priority.

From their weight alone it’s clear this ammo was made to perform as expected in a subsonic capacity. And since it’s designed by Fiocchi, you know what to expect.
