Federal Premium 40SW Hydrashok 165gr

Hydra-Shok 40 S&W

Federal Premium Personal Defense in 40 S&W is a self-defense load built around the Hydra-Shok hollow-point, the bullet Federal designed so that it opens reliably when it hits a target instead of punching straight through. Each box holds 20 centerfire pistol cartridges loaded with a 165-grain bullet, a standard weight for the caliber that balances recoil against stopping power. It suits anyone carrying a 40 S&W pistol for home or personal defense who wants proven expansion rather than range-grade ball ammo.

Features

• 40 S&W Chambering — Loaded for the 40 Smith & Wesson cartridge, so it fits any pistol marked for that caliber.
• 165-Grain Bullet — A mid-weight projectile for the caliber, measured in grains, that keeps recoil manageable while retaining defensive energy.
• Hydra-Shok JHP — A jacketed hollow-point with a center post inside the cavity that drives controlled expansion as the bullet passes through soft tissue.
• Notched Copper Jacket — The jacket is scored so it peels back into a wide mushroom on impact rather than staying closed.
• Centerfire Primer — The primer sits in the center of the case head, the reliable ignition system standard on defensive handgun ammunition.
• Brass Case — Reloadable brass cases that extract and feed cleanly in semi-automatic pistols.
• 20-Round Box — Packed 20 cartridges per box, the usual count for premium defensive loads.
• Factory Part P40HS3 — Federal's own catalog number for this specific load, useful when matching what you already carry.

Built For Defense

Hydra-Shok has been a benchmark defensive design since Federal introduced it, trusted by law enforcement and civilian carriers for its consistent performance. The center-post hollow-point and notched jacket work together to expand the bullet on impact and hold its weight as it penetrates, which is what separates a dedicated defense round from plinking ammunition. Pair it with your carry pistol and confirm it feeds and groups well from your own gun before relying on it.
