The Hornady FTX bullets have the patented Flex Tip design rendering them safe in tubular magazines found on most lever action guns. The Flex Tip technology delivers excellent terminal performance and controlled expansion across a broad range of velocities. Upon impact, the soft tip compresses into the bullet, initiating immediate expansion that transfers energy to the target for quick kills. The famous Interlock feature, locks the core and jacket, eliminating core and jacket expansion. The Hornady FTX delivers the flattest trajectories from both lever guns and revolvers alike.
