Fiocchi 308Sbra Hypermance ammunition is engineered specifically for short-barreled rifles and compact carbines where barrel length matters. Loaded with 125-grain Super Shock Tip bullets, this 308 Winchester round delivers optimized velocity and terminal performance from barrels ranging from 7.5" to 11.5"—ideal for AR-10 short-barrel builds, patrol carbines, and precision rifle platforms where space and weight are priorities. Each case is loaded with propellants selected to burn completely, minimizing muzzle flash and report while maximizing velocity from shorter tubes.

The Super Shock Tip projectile is built for reliable expansion and performance on game and targets alike. This ammunition is rated safe for use with suppressors, making it a solid choice if you're running a can on your short-barrel setup. You get 20 rounds per box, with cases offered in 10-box increments, so you can stock up for the range or field without breaking the bank.

Whether you're building a truck gun, home-defense rifle, or a lightweight hunting platform, Fiocchi's Hypermance line gives you ballistic tuning purpose-built for the shorter barrel you've chosen. It's a refreshing alternative to generic 308 Winchester loads that treat all barrel lengths the same.

Frequently Asked Questions

Will Fiocchi Hypermance work in a standard 308 Winchester rifle?

Yes. Hypermance is loaded to 308 Winchester specifications and is safe for any rifle chambered in that caliber. However, it is specifically optimized for short barrels; standard-length rifles will not benefit from the tuning designed for 7.5"–11.5" tubes.

Is this ammunition suppressor-rated?

Yes. Fiocchi Hypermance is formulated to be safe for use with suppressors.

What is included in a case?

Cases are sold in 10-box increments. Each box contains 20 rounds, making a full case 200 rounds of 308 Winchester Hypermance ammunition.

What makes this different from standard 308 ammunition?

Hypermance is engineered with propellants and timing selected to maximize velocity and terminal performance from shorter barrels (7.5" to 11.5") while minimizing muzzle flash and report. Generic 308 loads are not optimized for this shorter barrel range.
