Ballistics Table

Official-data note: Fiocchi publishes velocity and energy from a 16-inch test barrel and bullet path for a 100-yard zero through 300 yards. Wind drift is not shown.

Key takeaway: Fiocchi lists 2200 fps, 1343 ft-lbs, and G1 BC 0.305 for stock number 300BLKHA.

The Hornady SST Bullet in 300 Blackout

The Hornady SST (Super Shock Tip) projectile is a well-established hunting bullet that Fiocchi licenses for use in this Hyperformance line rather than manufacturing in-house. The defining feature is a red polymer tip seated in the hollow point cavity. On impact, this tip drives rearward into the lead core, initiating rapid and consistent expansion even at the lower velocities that a short 300 Blackout barrel may produce. The boat-tail base reduces base drag and improves stability in flight, contributing to the load’s advertised accuracy advantage over flat-base designs.

The SST’s secant ogive profile is optimized for a balance between aerodynamic efficiency and terminal expansion. In the context of 300 Blackout, where supersonic loads are typically used for hunting and the cartridge is designed around relatively modest velocity figures compared to larger rifle cartridges, the SST’s ability to expand reliably at impact velocities in the 1,500–1,900 fps range is a meaningful design advantage. This distinguishes it from match-grade open-tip bullets that may not expand reliably, and from bonded bullets that prioritize weight retention over rapid expansion. Hunters using this load on deer-sized game at moderate ranges are working within the bullet’s intended performance envelope.

Best Uses

Good fit:

• Whitetail deer and similar medium-sized game at ranges inside 200 yards from a rifle-length barrel
• Hunters running AR-15 platform rifles chambered in 300 Blackout who want a purpose-built hunting load
• Shooters who want a consistent, factory-loaded polymer-tip option without hand-loading
• Field situations where reliable terminal expansion at moderate impact velocities is required
• Hunters who want a 125 gr SST load with a published G1 BC and 100-yard-zero bullet path

Not the right tool for:

• Suppressed subsonic applications — this is a supersonic load and is not suited to quiet-fire configurations
• Long-range precision work beyond 300 yards, where the cartridge’s trajectory and retained energy become significant limiting factors
• Hunting large or dangerous game where deeper penetration and higher weight retention are required — a bonded or solid bullet would be more appropriate
• Jurisdictions with restrictions on lead-core hunting bullets — this load contains a traditional lead core
• Varmint or small game hunting where rapid fragmentation and minimal pelt damage are priorities — the SST is optimized for medium-game expansion, not varmint-style fragmentation

Reliability Notes

No structured submissions yet.

Based on manufacturer claims and open-source product information, the following notes are available — these are not structured, verified data:

• Fiocchi markets this load under its Hyperformance line, which the company positions as its premium hunting tier, implying tighter quality control and more consistent velocity spreads than their value-oriented lines. This claim is manufacturer-stated and has not been independently verified through structured chronograph submissions.
• The use of the Hornady SST projectile is a meaningful quality indicator, as it is a well-regarded component bullet with a documented track record in hunting applications across multiple calibers and manufacturers.
• Open-source shooter feedback on 300 Blackout SST loads generally reports consistent feeding in AR-platform rifles and reliable expansion on game, though these observations are not specific to this Fiocchi load and should not be attributed directly to it.
• No active recalls, safety notices, or documented lot-specific issues were identified for this product at the time of publication.
