Product DescriptionHornady Handgun Hunter ammunition is built for tough, real-world hunting conditions where reliable expansion and deep penetration matter. Each cartridge is loaded with Hornady's MonoFlex bullet, featuring a rugged copper-alloy construction designed to resist separation for consistent weight retention and straight-line penetration. A proprietary elastomer insert in the open cavity compresses on impact and then drives expansion, helping the bullet open more quickly across a range of velocities. Premium cases, primers, and powders round out this dependable hunting load for .40 S&W handguns.Product Highlights MonoFlex copper-alloy hunting bullet engineered for deep penetration and tough-game performance Elastomer-filled cavity promotes faster, more reliable expansion than standard hollow points Premium components (cases, primers, and powders) for consistent field performance .40 S&W centerfire handgun ammunition optimized for handgun hunting and backup use Convenient 20-round box for range confirmation and hunt-ready carrySpecs Brand: Hornady Product Line: Handgun Hunter Caliber: .40 S&W (.40 Smith & Wesson) Bullet Weight: 135 gr Bullet Type: MonoFlex (monolithic copper-alloy hollow point with elastomer insert) Cartridge Type: Centerfire pistol Case Material: Brass Primer: Boxer Muzzle Velocity: 1130 fps (4 in test barrel) Muzzle Energy: 383 ft-lbs G1 Ballistic Coefficient: 0.101 Rounds per Box: 20 Boxes per Case: 10 MPN: 91361 UPC: 090255913613Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
