Blemish ammunition may have either minor cosmetic imperfections caused by the manufacturing processes or an average velocity slightly less than the published velocity for the particular load. These imperfections do not create functional issues, but may result in slight performance variations from our standard ammunition. The cosmetic imperfections may include: discoloration of the case or projectile, small divot or scratch on the case, projectile or primer, deformation of the projectiles tip or missing polymer tip. Brass may not be nickel plated and the color of coated bullets may not match the product picture. All sales on blemish ammunition are final and no returns will be allowed.
