Federal HST – Premium Defensive Ammunition Trusted by Professionals

 When it comes to personal protection, reliability and terminal performance are critical. Federal HST ammunition has become one of the most trusted self-defense rounds used by law enforcement agencies and responsible civilian carriers worldwide. Engineered to deliver consistent expansion, optimal penetration, and dependable feeding, Federal HST sets the standard for modern defensive handgun ammunition. Whether for concealed carry, duty use, or home defense, Federal HST is designed to perform when it matters most.

In this guide, we’ll explore what makes Federal HST special, how it performs, available calibers, and why it remains a top choice for defensive shooters.



What Is Federal HST?

Federal HST is a premium jacketed hollow point (JHP) defensive ammunition line produced by Federal Premium Ammunition. Unlike traditional hollow points, HST bullets are designed to expand reliably through common barriers such as clothing, while still achieving deep, controlled penetration. The result is a round that delivers maximum stopping power without excessive over-penetration.

Federal developed HST to meet stringent law enforcement requirements, and it has since earned a reputation for consistent performance in real-world defensive situations.

Key Features of Federal HST Ammo

1. Consistent Expansion

One of the standout qualities of Federal HST is its reliable expansion. The bullet design prevents clogging and ensures the hollow point opens as intended, even after passing through heavy clothing.

2. Optimized Penetration

Federal HST is engineered to meet FBI penetration standards, striking a balance between penetration depth and expansion. This ensures effective energy transfer while reducing the risk of over-penetration.

3. Jacketed Hollow Point Design

The mechanically locked jacket and core help maintain bullet integrity, allowing the projectile to expand uniformly and retain mass for improved terminal performance.

4. Excellent Feeding Reliability

Federal HST rounds are known for smooth feeding in a wide range of pistols, including compact, subcompact, and full-size handguns. This reliability is essential for defensive use.

5. Law Enforcement Proven

Federal HST is widely issued to law enforcement agencies, a testament to its dependable performance under high-stress conditions.

Popular Federal HST Calibers

Federal HST is available in many of today’s most popular defensive handgun calibers, including:

  • 9mm Federal HST

  • .40 S&W Federal HST

  • .45 ACP Federal HST

  • .357 SIG Federal HST

  • 10mm Federal HST (select loads)

Each caliber is offered in multiple bullet weights, allowing shooters to select the load that best suits their firearm and recoil preference.

Why Choose Federal HST for Self-Defense?

Trusted Performance

Federal HST consistently ranks among the top defensive ammunition choices in ballistic testing. Its ability to expand reliably while penetrating to effective depths makes it ideal for real-world defense.

Reduced Risk of Over-Penetration

Compared to FMJ rounds, Federal HST’s controlled expansion helps reduce the chance of a bullet passing through the target and causing unintended damage beyond it.

Accuracy & Control

Versatile Use

Whether you’re carrying concealed, protecting your home, or using a duty firearm, Federal HST performs consistently across different barrel lengths and firearm platforms.

Compared to standard hollow points, Federal HST stands out for:

  • More reliable expansion

  • Better penetration consistency
