Product Overview
Fiocchi loads this 5.7x28mm round with a 62-grain FMJ bullet at 1,050 fps, well below the speed of sound. That heavier bullet weight is nearly double what most 5.7x28mm loads use. Muzzle energy sits at 152 ft-lbs from a brass case. The 0.23 G1 ballistic coefficient reflects the larger, heavier projectile profile compared to the lightweight 27-40 grain pills that dominate this caliber.
The subsonic velocity is the defining trait here. At 1,050 fps, this load stays below the sonic threshold and eliminates the ballistic crack that supersonic rounds produce. Paired with a suppressor, the noise reduction is dramatic. The 62-grain bullet also generates less felt recoil impulse shift than hot 5.7 loads, and the heavier projectile tracks more predictably through a suppressor's baffles. Fiocchi designed this round specifically for suppressed firearms, and it fills a gap that few other 5.7x28mm manufacturers address.
Suppressed range sessions are the primary application. Shooters running a can on an FN Five-seveN, Ruger-57, or PS90 SBR will get the quietest possible report from this load. It also works well at indoor ranges where lower velocity means less concussion in enclosed spaces. The FMJ construction and brass case make it a solid training option for shooters who want trigger time with their suppressed setup without burning through expensive defensive ammo. Target work inside 25 yards is where this round does its best work.
- True subsonic velocity at 1,050 fps eliminates the sonic crack when fired through a suppressor
- 62-grain bullet is nearly double the weight of standard 5.7x28mm loads, giving the projectile more momentum at close range
- Brass case allows for reliable reloading and consistent chamber extraction
- One of very few factory subsonic options available in 5.7x28mm
- FMJ construction feeds reliably in semi-auto platforms like the Five-seveN and Ruger-57
- 152 ft-lbs of muzzle energy is low, limiting this round to range and training use only
- The heavier 62-grain bullet may not stabilize well in all 5.7x28mm barrel twist rates optimized for lighter projectiles
- Reduced velocity means more bullet drop past 25 yards compared to standard 5.7 loads
- Not widely stocked, and availability can be inconsistent compared to standard-velocity 5.7x28mm ammo
