Tannerite Goliath Rimfire Targets have explosive effects for low-speed rimfire rifles. With a triangle shaped-charge Tannerite is one of the most powerful rifle targets yet. Once the target has been hit from 50 or more yards away a loud and powerful sound will echo through the field. This product includes a scoop mixing container catalyst and instructions. It's important to carefully read the instructions because this product has different properties than other Tannerite products. If used incorrectly this could pose a fire hazard or bodily harm.
