In short, no. In fact, every Hornady® 223 Rem and 5.56 NATO load is designed to penetrate less than most service pistol cartridges. Total penetration varies from as little as 5.5 inches from the 40 grain load to 15 inches from the 62 grain barrier load. All of these are equal to or less than the FBI’s maximum recommended penetration of 15 inches.
All Hornady® 223 and 5.56 loads are designed to expand rapidly when they come into contact with a soft medium. This allows for maximum wound cavitation and little risk of over-penetration.
