Birchwood Casey Dirty Bird 12x18in Blue/Orange Silhouette Target - 8 Pack - Birchwood Casey's Dirty Bird Silhouette target allows you to spot your shots easily with "intense white" splatter for superior downrange contrast. The heavy tagboard construction is great for indoor or outdoor use, and all types of pistol-action shooting. 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.
