Official Specs

All data verified against Hornady’s official ballistics chart and multiple established retailers.

⚠️ Retailer data error — Ammunition Depot: The listing used as reference for this page shows MV = 2,615 fps. This is incorrect. Per Hornady’s official ballistics chart, the velocity at 100 yards is 2,615 fps — Ammunition Depot has listed the 100-yard downrange velocity in the muzzle velocity field. The correct muzzle velocity is 2,820 fps, confirmed by Hornady’s ballistics PDF and multiple retailers (Able Ammo, Target Sports USA, Palmetto State Armory, DB Supply, MiWall). Similarly, the listing shows ME = 1,959 ft-lbs — this is the 100-yard energy figure, not muzzle energy. All specs on this page reflect Hornady’s official data.

Ballistics Table

From Hornady’s official ballistics chart (velocity data, 24″ barrel, SKU 81489). Zero: 100 yards. Sight height: 1.5″.

Key takeaway: at 2,820 fps from a 24″ barrel with BC 0.445 this is a solid value-tier deer hunting load. At 300 yards the InterLock carries 1,427 ft-lbs with 20.8 inches of drop — adequate for whitetail deer at typical hunting distances. The load follows Hornady’s “conventional velocity” philosophy for American Whitetail — reliable performance in any semi-auto or bolt-action without pressure concerns. At $1.55–1.65/round it is the most affordable Hornady factory hunting load in this 6.5 CM series.

The Hornady InterLock ISP Design

The Hornady InterLock is one of the most field-proven deer hunting bullet designs in North America — in continuous production for decades, it is the foundation of Hornady’s American Whitetail line:

• InterLock ring — a raised ring inside the jacket embedded in the lead core; mechanically locks jacket and core together during expansion; prevents core-jacket separation on bone impact; not chemically bonded but provides reliable core retention
• Secant ogive — a more aerodynamically efficient nose profile than tangent or round-nose designs; Hornady notes this as “our pioneering secant ogive design” — contributes to the published BC of 0.445
• Exposed lead tip (ISP — InterLock Soft Point) — traditional soft point mechanism; lead tip initiates expansion through hydraulic pressure on impact; reliable across impact velocities from close range to 300+ yards
• Semi-auto compatible — Hornady specifically notes the load is designed for consistent function in semi-automatic platforms, not just bolt-action rifles

The ISP designation distinguishes this from the SST (Super Shock Tip, polymer tip) version. The ISP is the traditional open soft point; the SST adds a polymer tip for higher BC and more aggressive expansion initiation.

American Whitetail in Hornady’s 6.5 CM Lineup

Hornady produces several 6.5 CM loads at different price and performance tiers. Where American Whitetail fits:

American Whitetail ISP is the entry-level option — least expensive, traditional bullet design, same velocity as standard SST loads but lower BC. For deer hunters who shoot inside 250 yards and prioritize cost, it delivers full value.

Best Uses

Good fit:

• Whitetail deer at 50–250 yards — Hornady’s explicit design target for this load; the InterLock at 2,820 fps delivers proven terminal performance at typical eastern and midwestern deer hunting distances
• Hunters who want Hornady’s own bullet and brass at the lowest available Hornady price
• Semi-automatic 6.5 CM platforms — American Whitetail is specifically designed for reliable function in semi-auto actions
• Pre-season practice where burning premium ELD-X rounds is wasteful — American Whitetail trajectory matches closely enough inside 200 yards for zeroing purposes
• Reloaders who want Hornady brass at a bargain price

Not the right tool for:

• Long-range hunting beyond 300 yards where the BC of 0.445 produces steeper drop than SST (0.527) or ELD-X (0.625) alternatives — at 400 yards the difference becomes practically significant
• Elk at difficult angles where a bonded bullet provides greater core retention insurance — InterLock is not bonded
• Lead-free requirements — lead-core construction
• Self-defense — not designed or rated for it

Reliability Notes

No structured submissions yet.

General notes:

• The Hornady InterLock has decades of field documentation on North American deer — it is one of the most extensively tested traditional hunting bullets available in factory form
• At 2,820 fps Hornady achieves their stated “compatible with semi-autos” goal; the load is within standard SAAMI pressure parameters
• Hornady brass is produced to consistent specifications and is well-regarded by reloaders; the American Whitetail line uses standard Hornady brass (not the premium Match-grade selection)
• The load has 7 verified reviews on the Ammunition Depot listing — all positive, consistent with the InterLock’s longstanding reputation for reliable deer performance

Competitors

Key comparison: Fiocchi Field Dynamics 129 gr PSP uses the same Hornady InterLock in a boat-tail configuration (BC ~0.485 vs 0.445 for this flat-base ISP) at a comparable price. The boat-tail gives Fiocchi a modest BC advantage at longer ranges. For hunting inside 250 yards, the practical difference is negligible. Hornady American Whitetail’s advantage is the Hornady brand name and their own brass.

Price Reality

• Typical retail range: $30–34 per box of 20 (~$1.50–1.70/round) — most affordable Hornady hunting load in this series
• vs. Federal Power-Shok / Remington Core-Lokt: comparable or $2–4/box more; Hornady offers slightly better-documented bullet construction at a similar price tier
• vs. Fiocchi Field Dynamics (same InterLock, BT version): comparable pricing for the boat-tail variant with higher BC — Fiocchi is the better long-range choice; Hornady wins on brand recognition
• The value case: at $1.60/round with Hornady brass and a proven InterLock bullet, this is the most compelling argument for budget-conscious deer hunters who want Hornady quality
• Fair price benchmark: under $33/box is excellent; the load frequently goes on sale below $30/box which makes it genuinely competitive with budget alternatives

Where to Buy

Hornady American Whitetail 6.5 Creedmoor 129 Grain ISP (Box)

The American Whitetail line by Hornady was designed specifically for the Whitetail Deer hunter. The Interlock bullet has a ring exclusive to Hornady that prevents the lead core from separating from the jacket, creating a devastating projectile with excellent mass retention.

FAQ

Why did one retailer list 2,615 fps as the muzzle velocity?

This is a data entry error. Per Hornady’s official ballistics chart, 2,615 fps is the velocity at 100 yards — not the muzzle velocity. The correct muzzle velocity is 2,820 fps. This type of error occurs when a retailer copies field data from a ballistics table but selects the wrong row. The muzzle energy listed (1,959 ft-lbs) is also the 100-yard energy figure. Hornady’s official data, confirmed by five independent retailers, consistently shows 2,820 fps muzzle velocity and 2,277 ft-lbs muzzle energy.

InterLock ISP vs InterLock BT — what’s the difference?

ISP (InterLock Soft Point) uses a flat base and exposed lead tip — the classic hunting bullet form. InterLock BT (Boat-Tail) adds a tapered rear section that reduces base drag, improving BC from ~0.445 to ~0.485 for the same 129 gr bullet weight. Fiocchi Field Dynamics (FIO65CMB) loads the BT version. At hunting distances inside 250 yards the trajectory difference is less than 2 inches — both perform adequately. Beyond 300 yards the BT’s BC advantage produces noticeably less drop and wind drift. For hunters who regularly shoot beyond 250 yards, the BT version is the better choice.

Is the InterLock appropriate for elk?

The InterLock ring provides mechanical core-jacket locking — better than a plain cup-and-core soft point but not chemically bonded. On elk at broadside shots inside 250 yards, the InterLock at 2,820 fps delivers adequate penetration. On heavy shoulder shots or quartering-to angles, bonded bullets (AccuBond, Terminal Ascent, Scirocco II) provide a larger safety margin. Hornady’s own press release notes this load is “well suited for North American game up to and including elk” — accurate within that context of reasonable shot placement.

Hornady American Whitetail vs Superformance — same InterLock, is it worth $0.55/round more?

Hornady Superformance (SKU 81496) uses the SST bullet (not InterLock) and runs 130 fps faster (2,950 vs 2,820 fps) with higher BC (~0.527 vs 0.445). At $0.55/round more it is not the “same InterLock at higher velocity” — it is a different, higher-performance bullet at a meaningful velocity advantage. For deer inside 200 yards, American Whitetail ISP is fully adequate and saves real money. For open-country hunting past 300 yards, Superformance’s SST is worth the upgrade.
