FTX rifle bullets features Hornady's patented Flex Tip bullet technology. It is safe to shoot in tubular magazines as well as any other firearm. Upon impact, the soft tip compresses into the bullet, initiates immediate expansion across a wide range of velocities. The InterLock Ring mechanically locks the core and jacket together for maximum weight retention and deep penetration. The ballistically-efficient secant ogive profile pioneered by Hornady delivers stability, flat trajectories and amazing accuracy. The specially engineered heavy jacket over the shank of the bullet combined with Hornady's proven InterLock design controls expansion and enhances accuracy. These are the same bullets loaded in LEVERevolution.
