Federal Premium HST 380 ACP 99gr JHP Personal Defense Ammo 20rd

The Federal P380HST1S Premium Personal Defense ammunition delivers consistent terminal performance through Federal's proven HST jacketed hollow point design. This 380 ACP load combines a 99-grain HST bullet with optimized powder charges to maximize expansion and penetration in compact pistols.

What Makes This Different

Federal's HST (Hi-Shok Two) technology sets this ammunition apart from standard hollow points through its mechanical bonding process that prevents jacket separation. The bullet design features a post in the center of the hollow point cavity that initiates expansion at lower velocities typical of 380 ACP cartridges. Independent ballistic testing shows HST bullets achieve 12-18 inches of penetration in ballistic gelatin while maintaining 95% weight retention.

Key Features

• 99-grain HST jacketed hollow point bullet optimized for 380 ACP velocities
• Mechanical jacket bonding prevents separation during expansion
• Nickel-plated brass cases resist corrosion and enhance feeding
• Low-flash propellant reduces muzzle signature in low-light conditions
• Consistent velocities across temperature ranges from -20°F to 120°F
• 20 rounds per box packaging with 10 boxes per case (200 total rounds)
• Compatible with all 380 ACP firearms including micro-compact pistols

This load generates approximately 900 feet per second muzzle velocity from a 3-inch barrel, providing reliable expansion while maintaining adequate penetration for personal protection scenarios. The HST bullet design performs consistently through heavy clothing and intermediate barriers. Federal's quality control processes ensure lot-to-lot consistency for predictable point of impact.
