Fiocchi 300 Blackout ammunition engineered specifically for short-barrel rifle platforms. The Hypermance line pairs 220-grain Nosler Boat Tail projectiles with propellant selection and charge weights optimized for barrels from 7.5" to 11.5"—the sweet spot where subsonic and transonic 300 Blackout rounds perform best. If you're running a short-barreled rifle, patrol carbine, or pistol with an arm brace, this ammunition is built to extract reliable terminal performance from a shorter sight radius and reduced powder column.
The 220-grain Boat Tail design delivers consistent, controlled energy transfer on game and steel. Fiocchi formulated these loads for complete powder burn, which means less muzzle flash, lower sound signature, and better velocity stability across the short-barrel spectrum. Suppressors remain a common pairing with subsonic 300 Blackout builds—this ammunition is safe for that application and won't degrade suppressor service life.
Delivered in boxes of 20 rounds, with a full case containing 10 boxes. Fiocchi's quality control and consistency make reloading data and ballistic prediction more reliable, which matters when you're dialing distance on a SBR or building a precision-accuracy setup. Whether you hunt, train, or compete with short-barrel platforms, Hypermance 300 Blackout removes the guesswork from ammunition selection.
