When you go out shooting, you want a reaction. That's why for years old cans and bottles were a favorite at the practice range. Until now! These revolutionary self-adhesive targets explode in color upon impact. And the bright yellow ring around the bullet hole is visible to the naked eye - allowing you shot after shot without interruption. So forget hunting for cans; load up on SHOOT-N-C targets and let the fun begin! All Shoot-N-C Targets are self-adhesive. To use, simply apply to an existing target or penetrable backstop. See bullet holes instantly, without the aid of spotting scopes or binoculars. Great for all firearms and calibers. Upon bullet impact, a bright yellow ring appears around each hole. Indoor/outdoor use. Excellent for those with reduced vision capabilities.
