Birchwood Casey® Shoot-N-C™ Self-Adhesive Shooting Targets allow you to immediately see how your gun is shooting, without taking the time to walk to the target and search for bullet holes. That's why old cans and bottles were a favorite for target practice for years—they reacted when hit. Birchwood Casey Shoot-N-C Shooting Targets explode in color upon bullet impact, creating a bright chartreuse ring around the point of impact. To use, simply apply these self-adhesive targets to an existing target, cardboard, or any penetrable backstop. See bullet holes instantly without the aid of spotting scopes or binoculars. These are great shooting targets for all firearms and calibers, for indoor ranges and outdoor use. To extend the life of your Shoot-N-C Targets, apply pasters over the shot marks. Pasters can also be used as single targets. Manufacturer model #: 34825.
