200 Rounds Hornady LE 8126N - 5.56 NATO 75 gr. BTHP T2 TAP in 20 round boxes - New Production Match Grade Police Patrol Round

Hornady Law Enforcement 5.56mm NATO 75-grain BTHP T2 TAP Precision (Product Code: 8126N).

If Black Hills owns the military contract spotlight with the MK 262, Hornady rules the law enforcement tactical space with their TAP (Tactical Application Police) lineup. The 8126N SKU represents their ultimate duty load for the AR-15/M4 platform—a high-pressure, heavy-match cartridge optimized explicitly for reliable feeding, extreme thermal stability, and immediate soft-tissue incapacitation.

Overview & The "T2" Bullet Profile

You might be familiar with Hornady’s standard 75-grain boat tail hollow points, but the 8126N utilizes their proprietary T2 projectile. The T2 features a subtly redesigned, slightly more tapered nose profile engineered specifically to eliminate feed-ramp hang-ups in fast-cycling, hard-use gas operated carbines.

• Caliber: 5.56x45mm NATO (High pressure; absolutely not for .223 Rem chambers)

• Bullet Weight: 75 grain

• Bullet Type: Boat Tail Hollow Point (BTHP) T2 Match with a cannelure (Open Tip Match design)

• Casing: Mil-spec hardness brass, fully annealed, staked and sealed primer pockets, sealed case mouth

• Muzzle Velocity: ~2,750 ft/s (from a standard 16-inch barrel)

• Muzzle Energy: ~1,261 ft-lbs

Performance and Ballistics

1. Devastating Fragmentation (The Wounding Mechanism)

The 8126N is deliberately unbonded, meaning the lead core and copper jacket are not welded together. While that sounds counterintuitive for a duty round, it is the secret to its lethality. When the hollow point strikes soft tissue, it yaws instantly, causing the bullet to burst into a massive cloud of high-velocity fragments within the first 2 inches of penetration. It transfers 100% of its kinetic energy rapidly, creating massive permanent wound cavities.

2. Textbook Tactical Penetration

Despite fracturing violently, the heavy 75-grain base of the bullet acts like a slug, continuing to drive deep through the tissue. In bare ballistic gelatin, it routinely hits between 13 to 14.5 inches of penetration. This falls precisely into the ideal FBI tactical window, giving patrol officers maximum threat-stopping capability without the liability of over-penetration in urban environments.

3. Temperature-Stable Propellant Technology

A major hazard for duty ammunition is environmental variance—ammo left inside a police cruiser trunk in freezing winter conditions or a scorching summer day can experience dangerous pressure spikes or drops. Hornady loads the 8126N with highly advanced, custom-blended, temperature-stable powders. Whether it is -10°F or 110°F outside, your point of impact and muzzle velocity remain remarkably uniform.

Pros & Cons

Pros

• Flawless AR-15 Cycling: The T2 tapered ogive ensures ultra-smooth feeding even when dry, dirty, or scraping up steep ramps in short-barreled carbines.

• Match-Grade Sub-MOA Precision: Built to Hornady’s demanding "TAP Precision" standards; easily holds tight, match-winning groups out to 300–400 yards.

• Low Muzzle Flash: Custom powder blend includes heavy flash suppressants to protect your low-light night vision during indoor or defensive encounters.

• Mil-Spec Environmental Sealing: Staked and lacquer-sealed primers ensure the round will fire reliably even after being exposed to rain, oil, or extended storage.

Cons

• Not Barrier-Blind: Because the T2 bullet is designed to fragment violently on soft tissue, it performs poorly against hard obstacles like automotive safety glass or sheet metal. If your primary mission requires punching through car doors, look to a solid monolithic solid or a bonded round.

• Barrel Twist Restricted: The heavy, long 75-grain profile requires a fast 1:7" or 1:8" barrel twist to stabilize properly. While it can run acceptably in some 1:9" setups, do not attempt to shoot it through slow 1:12" twist barrels.

• LE Restrictive Availability: Officially designated as a Law Enforcement catalog item, making it difficult to source outside of dedicated surplus dealers or specialized vendors.

The Verdict

The Hornady 8126N (75gr TAP T2) is a legendary police patrol and close-quarters entry load. If your primary defensive rifle is a modern, fast-twist carbine and your goal is match-grade precision coupled with immediate, explosive soft-tissue stopping power, this is one of the single finest 5.56mm cartridges ever put into production.

• The Takeaway: AI can sometimes make mistakes, but it's never a mistake to order from Eagle Eye Guns.
