Hornady Superformance .308 Winchester 165 Gr SST

At a Glance

Official Specs

Note on BC G7: Hornady publishes a G1 BC for this load but does not list a G7 figure in their standard product data. For long-range trajectory calculations, a rough G7 equivalent can be derived by dividing the G1 value by approximately 2.0–2.3, but any such figure would be an estimate and is not presented here as a published spec.

Note on muzzle velocity source: Hornady states this velocity was measured from a 24-inch test barrel. Rifles with shorter barrels (e.g., 20–22 inches) will typically yield 30–60 fps less per inch of barrel removed from the test standard.

Key takeaway: The Hornady Superformance 165 gr SST in .308 Winchester holds supersonic flight well past 500 yards, retaining over 1,400 ft-lbs of energy at that distance — more than sufficient for ethical deer-sized game at extended field ranges. The Superformance propellant system produces a velocity advantage of roughly 100–200 fps over standard .308 loads at the same bullet weight, which meaningfully flattens the trajectory between 200 and 400 yards. Hunters engaging targets beyond 300 yards will notice the reduced holdover compared to standard-velocity .308 ammunition. Wind drift, not drop, becomes the dominant variable past 400 yards with this load.

The SST Bullet and Superformance Propellant System

The SST (Super Shock Tip) bullet is one of Hornady’s core hunting projectiles. It uses a red polymer tip seated in a lead-core, gilding-metal-jacketed body. The tip serves two functions: it improves the ballistic coefficient by streamlining the nose profile, and it initiates controlled expansion on impact by driving rearward into the lead core. The jacket is tapered and cannelured to produce a controlled mushroom across a wide range of impact velocities — important for a load designed to function from close-range shots at higher retained velocity all the way out to longer ranges where velocity has dropped.

The Superformance designation refers to Hornady’s proprietary propellant blend, which is formulated to produce higher velocities than standard powder charges without exceeding safe pressure limits. The chemistry is optimized for temperature stability, which reduces the velocity variation that can occur between cold-morning and midday shots during a hunt. This is not a standard factory load running standard powder — the velocity advantage is real and documented, and it matters most in the 200–400 yard engagement window typical of open-country deer and elk hunting.

Best Uses

Good fit:

• Whitetail and mule deer hunting at ranges from 50 to 400 yards
• Elk and black bear hunting where shots are expected inside 300 yards
• Open-country hunting where a flatter trajectory compared to standard .308 loads reduces ranging error margin
• Hunters who want a polymer-tipped bullet for reliable feeding in semi-automatic or box-magazine bolt-action rifles
• Situations where the same rifle is used for both medium and larger game and a single load must perform across a range of impact velocities

Not the right tool for:

• Varmint or predator hunting — the 165 gr SST is too heavy and too expensive for high-volume small-game use
• Jurisdictions with lead-free ammunition regulations (California, some national parks) — the SST uses a traditional lead core and does not qualify as a non-toxic projectile
• Extreme long-range precision shooting past 600 yards where a higher G7 BC bullet (e.g., ELD-X or ELD Match) would be more appropriate
• Hunters specifically seeking a bonded bullet for heavy bone and deep penetration on the largest dangerous game — the SST is a cup-and-core design, not a bonded or monometal bullet

Reliability Notes

No structured submissions yet.

From manufacturer claims and open sources: Hornady describes the Superformance line as designed for consistent primer ignition and minimal velocity variation across temperature ranges, which is relevant for hunters in cold-weather conditions. The SST bullet’s polymer tip is reported to resist deformation in magazine stacking, which is a noted failure mode for some soft-point designs. The brass cases are Boxer-primed and described by Hornady as suitable for reloading after firing, though this is a factory ammunition reference only. No feed or extraction failures specific to this load have been identified in open-source reporting. These notes come from manufacturer claims and general open-source discussion, not structured performance submissions.

Price Reality

• Typical retail range: $42–$50 per 20-round box; case pricing (typically 10 boxes/200 rounds) runs approximately $420–$480 when available
• Per-round cost: approximately $2.10–$2.50 depending on retailer and timing
• The Remington Core-Lokt Tipped 165 gr is the clearest budget alternative, running $12–$15 less per box for a broadly similar polymer-tipped cup-and-core design — the difference is real velocity advantage and Hornady’s quality control reputation
• Federal Vital-Shok Trophy Bonded Tip and Nosler Trophy Grade Partition both run $5–$15 more per box and offer bonded construction, which is a meaningful upgrade for elk and bear hunters who prioritize deep penetration
• Fair price benchmark: $45–$50 per box is market-normal for this load. Prices above $55 per box for a standard 20-round box represent overmarket pricing and are not justified by the product tier

FAQ

Does the SST bullet expand reliably at the lower impact velocities encountered at 400–500 yards?The SST polymer tip is designed to initiate expansion at impact velocities as low as approximately 1,600 fps, which the Hornady Superformance load at 165 gr retains well past 500 yards under standard conditions. At 500 yards, this load is still moving at roughly 1,971 fps according to calculated trajectory data, leaving a substantial margin above the minimum expansion threshold. For deer-sized game within 400 yards, expansion reliability is not a concern with this bullet. At extreme ranges beyond 500 yards in cold weather or high altitude, confirming retained velocity against the minimum expansion threshold is worth doing before relying on the load.

How does the Superformance 165 gr SST compare to the Hornady Precision Hunter 178 gr ELD-X in .308 Winchester?These are two different tools within Hornady’s own lineup. The 165 gr SST Superformance offers higher velocity and a flatter trajectory inside 300 yards, making it a better choice for hunters who shoot at mixed distances and want reduced holdover. The 178 gr ELD-X Precision Hunter has a significantly higher BC (0.552 G1 vs. 0.447 G1), which means it resists wind drift better and retains energy more efficiently past 400 yards — but it starts slower. For most whitetail hunters shooting inside 300 yards, the SST Superformance is the more practical choice. For open-country hunters regularly engaging past 400 yards, the ELD-X becomes more competitive.

Is this load legal for hunting in California or other lead-restricted zones?No. The Hornady SST uses a traditional lead core and does not qualify as a non-toxic or lead-free projectile under California’s AB 711 regulations, which require lead-free ammunition for all hunting statewide. Hunters in California, certain national parks, and other jurisdictions with lead-free requirements should look at alternatives such as the Barnes VOR-TX 168 gr TTSX, which uses an all-copper monometal bullet. Always verify local regulations before purchasing hunting ammunition.

What is the effective hunting range of this load for elk?For elk-sized game, most experienced hunters and ballisticians recommend a minimum of 1,500 ft-lbs of retained energy and a terminal velocity sufficient for reliable expansion. This load retains over 1,900 ft-lbs at 300 yards and over 1,400 ft-lbs at 500 yards. The energy threshold is met comfortably at practical elk hunting ranges. However, the SST is a cup-and-core design, not a bonded bullet, and penetration depth on heavy-boned elk at close range (under 100 yards) where impact velocity is highest may not match a bonded or partition bullet. For elk inside 200 yards with potential for heavy-shoulder shots, a bonded alternative such as the Federal Trophy Bonded Tip or Nosler Partition is worth considering.

What barrel length is this load optimized for, and does it matter?Hornady’s published 2,840 fps muzzle velocity is measured from a 24-inch test barrel. Most hunting rifles in .308 Winchester use 20–22 inch barrels, which will typically yield 40–80 fps less than the published figure — roughly 2,760–2,800 fps from a 22-inch barrel. This is a modest reduction that does not meaningfully affect performance inside 400 yards. The Superformance propellant blend is formulated to be efficient across a range of barrel lengths, and the velocity advantage over standard .308 loads remains even in shorter barrels. Hunters using 18-inch tactical-profile barrels may see a slightly larger velocity reduction and should account for that in trajectory calculations.
