Overview
Hornady’s Critical Duty load is built for shooters who want a defensive .357 Magnum option suited to a full-size handgun and barrier-focused use. The 135-grain FlexLock bullet is described as combining a Flex Tip with an InterLock band to support controlled expansion and help keep the bullet and core together. Bright nickel-plated cases are intended to make chamber checks easier in reduced light, and the low-flash propellant is included to help preserve night vision during low-light firing. Packaged 25 rounds per box, this ammunition is aimed at serious personal protection use rather than general plinking.

- Designed for full-size handguns, so it may not be the most practical choice for compact revolvers or lighter carry setups.
- The 25-round box count is relatively small, which may require more frequent restocking for range use or reserve supply.
- Its barrier-penetration focus makes it a specialized defensive load rather than a general-purpose .357 Magnum option.
- Nickel-plated cases and low-flash propellant are useful in defensive contexts, but they add features that may be unnecessary for routine practice ammunition.
