Birchwood's Darkotic zombie target explodes with each hit in a white or neon green halo around the bullet hole, so you instantly know where you hit the target. Shots specific to the head area result in a highly-visible neon green halo. With full-color images, these 12" x 18" splattering, paper targets are so realistic, you'll think the zombie apocalypse has begun. They are great for use with all firearms and calibers.
