Best Uses

Use this box with a suppressor for quiet range time. A subsonic bullet avoids the sonic crack, so the can does more of its job. The heavy 62 grain bullet also changes your point of impact, so check your zero with it. Some pistols need a certain power level to cycle, so test a few magazines before a big session. Without a suppressor it is still loud, so wear hearing protection. Fiocchi 5.7 subsonic is FMJ, so keep it for range use.

Will subsonic 5.7 cycle my gun?
Many 5.7 guns run subsonic loads, but not all. Test a few magazines in your pistol or carbine before you rely on it.

What suppressor for 5.7×28?
Many 22-caliber rifle suppressors fit 5.7×28 hosts if rated for it. Check the maker’s caliber rating and your thread pitch first.
