The InterLock Ring – a Hornady exclusive – ensures that the core and jacket remain locked during expansion. The InterLock retains more mass energy and momentum after impact and transfers that energy to the target. Its reliable stopping power has earned the InterLock a worldwide reputation as a bullet for serious hunters. 

As with all of Underwood Ammo rounds we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
