Hornady 91376 Critical Duty 40 S&W 175 gr Hornady FlexLock (FL) 20 Per Box/ 10

Critical Duty features a high-antimony lead core that is extremely tough and delivers controlled expansion. It also provides a more economical choice than similar bonded bullets. The FlexLock bullet incorporates two revolutionary Hornady features: the no-clog, patented Flex Tip design and the heavy-duty jacket-to-core InterLock band. It utilizes a large mechanical jacket-to-core InterLock band that keeps the bullet and core from separating for maximum weight retention and proven terminal performance through. Nickel plating resists corrosion and greatly enhances low-light chamber checks while combining the cannelured bullet with a crimped case ensures no bullet setback during feeding.
