Birchwood Casey has been making products for serious shooters since 1948. The Dirty Bird 3-Gun Nation targets are the perfect target for the shooter looking to practice for any 3-gun competition. These innovative targets reveal a white splatter that appears upon bullet impact that allows the shooter to easily spot each shot instantly. One of the great features about this target is that they feature two scoring areas. A primary "A" zone that is 8" and a secondary "B" zone that is 17.25". making them a perfect target for practicing for your upcoming 3-gun match. One hit in the "A" zone is considered a neutralized target or any two hits anywhere in the "B" zone.
