Federal product overview (manufacturer description)
Federal describes the Personal Defense HST line as ammunition engineered for consistent expansion, optimum penetration, and reliable terminal performance, and lists HST as a law-enforcement duty load. According to Federal:
- The specially designed hollow point is built to expand reliably through a variety of barriers and resists plugging as it passes through them.
- Expanded diameter and weight retention are designed to reach the penetration wanted for personal defense without overpenetrating; Federal states the jacket and core hold together for nearly 100 percent weight retention.
- Federal cites superior performance in the FBI test protocol that agencies use to assess and select duty ammunition.
- A specific bullet nose profile, a nickel-plated case, and a high-performance primer are specified for function and reliability.
These are Federal’s published statements, presented here for reference and attributed to the manufacturer. Independent ballistic-gel tests of HST loads are widely available for third-party results.
