Reloadable blank primer strips are sold in a quantity of 8 per pack.APS Primer Strips are color-coded to prevent confusion and misidentification. To minimize the number of colored primer strips, we not only used the various colors for designating primer type but also for primer size. For example, there are two white primer strips; one for large pistol primers and one for small pistol primers.#250 Large Rifle, Magnum 88514
