FTX bullets are the same bullets that are loaded in the most popular lever gun ammunition ever devised: LEVERevolution. These technologically advanced bullets feature their patented Flex Tip 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 these firearms. Another benefit of Flex Tip technology is devastating terminal performance. Upon impact, the flexible tip deforms back into the bullet initiating violent, controlled expansion that transfers a great deal of energy to the vitals. At the same time, 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.
