Hornady's FTX Handgun bullets achieve reliable expansion over a wide range of velocities. Upon impact, the patented FTX tip is compressed into the front of the bullet, causing the bullet to expand and transfer immediate energy for a devastating temporary cavity, even at low velocity. It untilizes an InterLock Ring which mechanically locks the core and jacket together for maximum weight retention and deep penetration. The secant ogive profile delivers stability, flat trajectories and amazing accuracy, while the heavy jacket over the shank of the bullet is combined with Hornady's proven InterLock design.
