The Do All Outdoors ISHB4 Hot Box Self-Healing Target was originally designed for military, law enforcement and fast-action pistol training. This self-healing target is unpredictable and challenges the shooter to locate and readjust for every shot. The hot box target will fly, bounce, roll and run every time it is shot. The material of the self-healing target is technologically advanced to handle thousands of rounds from .22-.50 caliber rifles, pistols and shotguns.
