The Dirty Bird Targets reveal a white ?splatter' that appears upon bullet impact, which allows you to easily spot each shot. The non-adhesive back also allows you to affix to a surface as you wish, add notes and then easily save the targets for future reference. This target designed with 3-Gun Nation features two scoring areas - a 17.25" secondary, or "B" zone and an 8" primary, or "A" zone. One hit in the "A" zone is considered a neutralized target, or two hits anywhere in the "B" zone..
