Description
The Hornady 5.7×28 40gr FTX load is built for shooters who want more from their 5.7x28mm than typical factory ammunition delivers. Hornady loads a 40 grain Flex Tip eXpanding to a rated 1810 feet per second, producing about 291 foot-pounds of energy. Hornady Critical Defense uses the FTX bullet, whose soft polymer tip fills the hollow point cavity to prevent clogging with heavy clothing and to initiate consistent, reliable expansion at personal-defense ranges.

Buying ammunition by the box from the same production lot keeps velocity and point of impact consistent from one range trip to the next. Keep a record of the load you carry, check your ammunition for dents or loose bullets from time to time, and rotate your carry rounds so the ones in your firearm stay fresh. These simple habits help you get the full performance Hornady builds into every cartridge.
Before you trust any new load, fire enough rounds through your firearm to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Full-power loads produce more recoil and muzzle blast than typical range ammo, so practice with the Hornady 5.7×28 40gr FTX until you are comfortable with it, and store the rest in a cool, dry place in the original box.
About the 5.7x28mm
The 5.7x28mm was developed by FN Herstal in the 1990s for the P90 personal defense weapon and later the Five-seveN pistol. It launches a light, fast bullet with very little recoil, and today it is chambered in a growing range of pistols and carbines from FN, Ruger, Smith and Wesson and others. Ammunition costs more per round than 9mm, so it is worth confirming what your firearm prefers before buying in bulk.
