Who This Is For
Hornady Critical Duty 357 Mag is designed for law enforcement officers, armed security professionals, and responsible civilians who carry a full-size revolver or lever-action carbine for personal protection.

Frequently Asked Questions
How does the FlexLock bullet differ from a standard hollow point?
Traditional hollow points can plug with material when passing through intermediate barriers like clothing or auto glass, preventing proper expansion. Hornady's FlexLock bullet features a patented Flex Tip insert that resists plugging and initiates reliable expansion even after passing through common urban barriers. The InterLock band also mechanically locks the jacket to the core, ensuring the bullet retains its weight and drives deep into the target for consistent terminal performance.
Is this ammunition suitable for both revolvers and lever-action rifles chambered in 357 Magnum?
Yes. Hornady Critical Duty 357 Magnum is safe to fire in any firearm chambered for the 357 Magnum cartridge, including revolvers and lever-action rifles. Keep in mind that muzzle velocity will vary depending on barrel length — longer barrels will generally produce higher velocities, while snub-nose revolvers may see reduced performance. For optimal barrier-blind performance, Hornady recommends use in full-size handguns with a barrel length of 4 inches or more.
How should I store this ammunition and what is its shelf life?
Store Hornady Critical Duty ammunition in a cool, dry location away from direct sunlight, extreme heat, and humidity. When stored properly in its original packaging, modern brass-cased, Boxer-primed ammunition like this can remain reliable for ten years or more. Avoid storing ammo in vehicle glove boxes or areas subject to temperature extremes, and always inspect cartridges for signs of corrosion or damage before loading them for carry or duty use.
