Federal Premium HST 45 ACP 230gr JHP — 500 Rounds

The Federal HST 45 ACP is the law enforcement duty load in the .45 ACP category.

A 230-grain HST JHP at 890 fps and 405 ft-lbs, designed to pass FBI protocol testing and deployed by law enforcement agencies worldwide.

At $0.76 per round for 500 rounds, the Federal HST 45 ACP is the most cost-effective premium defensive load in the .45 ACP category.

The HST Hollow Point Design

The defining challenge for defensive hollow points is barrier performance.

Soft material — heavy denim, leather, wadded clothing — can pack into a standard hollow point cavity on entry, preventing expansion. The plugged bullet then behaves like FMJ, penetrating without opening.

The Federal HST 45 ACP bullet is engineered to prevent plugging.

The cavity geometry and jacket scoring ensure barriers cannot block expansion. The hollow point opens reliably through bare gel, heavy clothing, and other barriers in the FBI test sequence.

Weight retention is the second HST design priority.

The jacket and core are bonded — not a conventional press-fit — so the expanded bullet retains near-100% of its original weight. No jacket separation, no core loss.

FBI Protocol Performance

The Federal HST 45 ACP performs to the FBI test protocol — the standardized sequence used by law enforcement to evaluate and select duty loads.

The protocol tests penetration through bare gel, heavy clothing, auto glass, wallboard, and plywood at specified ranges.

Federal HST is used by law enforcement agencies across the United States as a standard issue duty load.

Nickel-Plated Case

The nickel-plated brass case provides corrosion resistance for carry ammunition stored in holsters and magazines for extended periods.

The nickel finish also feeds more smoothly than bare brass in tight-tolerance semi-automatic actions.

Frequently Asked Questions

What is Federal HST and why is it used by law enforcement? HST (Hydra-Shok Technology) is Federal’s premium defensive hollow point, developed to FBI protocol specifications and widely adopted as a law enforcement duty load. It’s engineered for two things specifically: reliable expansion through barriers (clothing, glass, common materials) without plugging, and near-100% weight retention after expansion. These are the two primary failure modes of conventional JHP designs that the FBI protocol tests.

What does “barrier blind” mean for a hollow point? It means the bullet expands reliably regardless of what it passes through first. Conventional hollow points can be “blinded” by soft barriers — the cavity fills with denim or leather before reaching the target, and the plugged bullet penetrates without opening. HST’s cavity geometry and jacket scoring prevent plugging, so the bullet expands whether preceded by bare skin or heavy clothing.

How does Federal HST compare to the Federal Syntech Defense SHP in this category? Two different defensive philosophies at two different price points. HST at $0.76/round is a conventional JHP that expands into a single mushroomed projectile with maximum retained weight. Syntech Defense at $1.00/round segments into three petals plus a core. For buyers who want the established law enforcement standard, HST is it; for buyers who want the multi-channel terminal approach, Syntech Defense is the alternative.

What makes the HST different from a standard hollow point? The cavity geometry is specifically designed to resist plugging from barriers. The jacket and core are bonded (not press-fit), which prevents jacket separation during expansion and maintains the bullet’s integrity through the full penetration channel.

What does FBI protocol testing cover? Penetration through bare ballistic gel, heavy clothing over gel, auto glass, wallboard, and plywood — all at specified ranges and angles. Depth of penetration (12–18 inches is the benchmark) and expansion diameter are measured for each test.

Is the brass reloadable? Yes — nickel-plated brass, Boxer primer.

How many rounds is 500? 25 × 20-round boxes.

What’s the per-round cost? $380 / 500 = $0.76 per round.
