At a Glance

Official Specs

Note: Fiocchi does not publish muzzle velocity or muzzle energy figures for this specific Hyperformance load in publicly available product documentation. The ballistics table below uses the well-established published performance data for the Hornady SST 180 gr projectile in .308 Winchester as a reference baseline. All values are calculated estimates and should not be treated as manufacturer-confirmed specifications. Community-submitted chronograph data would improve the accuracy of this page.

Ballistics Table

Calculated estimate. Real-world results vary by barrel length, temperature,altitude, and lot. Community submissions will provide measured muzzlevelocity for comparison.

Baseline reference: 2,620 fps muzzle velocity — consistent with published Hornady SST 180 gr .308 Win performance from a 24" test barrel. Actual velocity from hunting-length barrels (20–22") will be lower.

Zero: 100 yards | Sight height: 1.5" above bore

Note: All values marked ~ are calculated estimates based on a G1 BC of approximately 0.480, which is the published value for the Hornady SST 180 gr projectile. Because Fiocchi has not published a muzzle velocity for this load, these figures cannot be verified against factory data.

Key takeaway: At the estimated performance level, this load delivers over 1,300 ft-lbs of energy at 500 yards — well above the commonly cited 1,000 ft-lb threshold for ethical deer-sized game harvests. The SST’s polymer tip initiates reliable expansion even at reduced downrange velocities. For most hunters working inside 300 yards, trajectory management is straightforward. Beyond 400 yards, confirmed chronograph data from your specific rifle would be necessary before relying on these numbers in the field.

The Hornady SST Bullet in Fiocchi’s Line

The Hornady Super Shock Tip (SST) is a purpose-designed hunting projectile that Hornady licenses to other ammunition manufacturers, including Fiocchi. The red polymer tip serves two functions: it protects the hollow point cavity from deformation during feeding and magazine cycling, and it initiates rapid, consistent expansion on impact by driving rearward into the lead core. The InterLock ring — a mechanical feature molded into the jacket — anchors the core and jacket together under stress, promoting controlled expansion and limiting fragmentation. This is not a bonded bullet in the traditional sense, but the InterLock system provides meaningful weight retention compared to conventional cup-and-core designs. For hunters, this means the SST is engineered to expand reliably across a broad velocity range, which is particularly relevant for 308 Winchester loads used at both close and extended distances. Fiocchi’s Hyperformance line positions this component bullet inside a quality-controlled brass case with consistent powder charges, aiming to deliver match-adjacent accuracy alongside terminal performance.

Best Uses

Good fit:

• White-tailed deer hunting at ranges from 50 to 300 yards
• Mule deer and pronghorn in open terrain where shots may extend past 200 yards
• Black bear hunting where moderate penetration and controlled expansion are appropriate
• Hunters who need a single load that performs reliably across a wide velocity window
• Bolt-action and semi-automatic platforms chambered in 308 Winchester (7.62×51 NATO)
• Hunters prioritizing weight retention and mushroom consistency over deep penetration

Not the right tool for:

• Elk, moose, or large bear where deep, controlled penetration is a priority — a bonded or monolithic bullet is a stronger choice at this weight
• Shots through heavy shoulder bone on large-bodied animals where jacket separation is a concern
• States or units with lead-free ammunition regulations — the SST contains a lead core
• Target shooting or precision long-range competition — premium match bullets are better suited
• Varmint hunting — the 180 gr weight and construction are not optimized for small, thin-skinned animals

Reliability Notes

No structured submissions yet.

Based on manufacturer claims and open-source product information: Fiocchi’s Hyperformance line is described as a premium tier within their hunting ammunition catalog, with emphasis on consistent primer seating, uniform powder charges, and tight dimensional tolerances. The SST projectile is a commercially proven bullet component with an extensive track record across multiple ammunition brands. Hunters who have used SST-loaded ammunition from other manufacturers commonly report clean mushrooming and moderate weight retention on deer-sized game. No specific failure modes, lot-related inconsistencies, or reliability concerns for this Fiocchi load appear in publicly available sources as of the time of writing. All notes here derive from manufacturer claims or open-source commentary — not structured chronograph or terminal performance data collected under controlled conditions.

Price Reality

• Typical retail range: $34.99–$39.99 per box of 20 — approximately $1.75–$2.00 per round
• Per-round cost at $36.99: $1.85/round
• The Hornady American Whitetail 180 gr and Federal Power-Shok 180 gr typically run $1.30–$1.60/round — roughly $0.25–$0.55 cheaper per round for hunting-grade performance
• The Hornady Precision Hunter 178 gr ELD-X and Federal Trophy Bonded 180 gr command $2.10–$2.75/round — meaningfully more expensive and justified by bonded or high-BC construction for demanding applications
• At $1.85/round, this Fiocchi load sits in the mid-premium tier — appropriate for the SST component bullet and Hyperformance quality controls, but buyers expecting bonded-bullet performance at this price point should note the SST uses an InterLock ring, not a chemically bonded core
• Fair price benchmark: $36–$40/box is reasonable for this construction. Prices above $42/box for a 20-round box of this load would represent a premium that is difficult to justify against direct competitors

FAQ

Does the Fiocchi Hyperformance 308 Win 180 gr SST use the same bullet as Hornady’s own ammunition?Yes — the Hornady SST (Super Shock Tip) projectile used in this load is the same component bullet that Hornady loads in its own hunting lines. Hornady manufactures and licenses the SST to other ammunition producers, including Fiocchi. The bullet design, including the red polymer tip and InterLock ring, is identical. What differs between brands is the powder charge, primer selection, and case quality — all of which affect velocity, pressure consistency, and accuracy from a given rifle.

Is 180 grains the right bullet weight for deer hunting with a 308 Winchester?The 180 gr weight is at the heavier end of the practical range for .308 Winchester on deer-sized game. It delivers excellent downrange energy retention and is well-suited for larger-bodied deer, black bear, and medium-to-large game where deeper penetration is beneficial. Hunters shooting in dense timber at close range often prefer 150–165 gr loads for a flatter trajectory, while those hunting open country at extended distances may appreciate the higher sectional density of the 180 gr for wind resistance and retained velocity. Neither weight is wrong — the choice depends on terrain, typical shot distance, and target species.

How does the SST’s InterLock system compare to a fully bonded bullet for large game?The InterLock ring is a mechanical feature — a raised band inside the jacket that interlocks with the lead core to resist separation under high-velocity impact. It provides meaningful improvement over plain cup-and-core bullets in weight retention, but it is not equivalent to chemically bonded designs like the Federal Trophy Bonded Tip or Nosler Partition. For deer, hogs, and black bear, the SST’s performance is generally sufficient. For elk, moose, or large bear where shots through heavy bone or quartering angles are common, a fully bonded bullet offers greater confidence in consistent penetration and weight retention.

Will this ammunition function reliably in semi-automatic 308 platforms like the AR-10 or M1A?The 308 Winchester cartridge is dimensionally compatible with rifles chambered in 7.62×51 NATO, though shooters should confirm their specific rifle’s chamber specifications. The Fiocchi Hyperformance line is loaded to SAAMI 308 Winchester standards. Brass-cased, Boxer-primed ammunition of this type generally feeds reliably in semi-automatic platforms designed for the cartridge. The SST’s polymer tip is robust enough to withstand the feeding dynamics of semi-auto actions without deforming the tip or compromising terminal performance.

Why doesn’t Fiocchi publish muzzle velocity for this load?This is a common gap in mid-tier and even some premium factory ammunition lines. Some manufacturers publish velocity only for select SKUs, or list data that reflects a specific test barrel length (typically 24") without making that information easy to find on retail product pages. For the Fiocchi Hyperformance line specifically, velocity data does not appear in widely available product documentation. Hunters who need confirmed velocity data — particularly for extended-range shooting or ballistic solver inputs — should chronograph the load from their own rifle. A 22" hunting barrel will typically produce 40–80 fps less than a 24" test barrel, which has a measurable effect on trajectory and terminal velocity at distance.
