With Tannerite Exploding Binary Rifle Targets, there’s no question when your bullet hits its mark! Targets erupt with a showy flash and loud bang when hit, yet Tannerite is 100 percent safe when used as directed. The unique compound is exceptionally stable when subjected to less-severe forces such as a hammer blow, being dropped, or shot with a rimfire. For an additional layer of safety, Tannerite targets are supplied as two powders that, when carefully combined as indicated in the instructions, produce an explosive target. The two individual components are safe and inert on their own and will not explode until mixed together. Tannerite detonations only occur when the target is hit with a high-velocity centerfire bullet, producing a large explosion and cloud of water vapor. In addition to being just plain fun, this is particularly useful for long-range shooting practice, as you get immediate feedback when a target is hit. The Tannerite ProPack includes 20 half-pound targets, mixing container and instruction manual and DVD.
