FTX bullets are the same bullets that are loaded in the most popular lever gun ammunition ever devised: LEVERevolution. These technologically advanced bullets feature Hornady's patented FlexTip technology, which means they are safe to shoot in firearms with tubular magazines as well as any other firearm. Not only are they safe, they also deliver the flattest trajectories ever from lever guns. Another benefit of FlexTip technology is devasting terminal performance. Upon impact, the soft tip compresses back into the bullet initiating immediate expansion that transfers a great deal of energy to vitals. The heavy jacket over the shank of the bullet and famous InterLock feature keep the core and jacket physically locked together to ensure deep penetration for quick kills no matter what.
