If you are a new reloader or are not familiary with the term, please read our article "What is Once Fired Brass". In a nutshell, Once Fired Brass (OFB) is NOT new brass, but an ammunition/firearms industry term that loosely describes used reloading brass cases. Although called “once” fired, the actual number of times fired is unknown. This range brass includes both commercial and military casings. Brass is washed, then sorted by size and steel/aluminum/Berdan primed cases removed. Once fired reloading brass cases are mixed commercial, military and foreign, headstamps (usually shown in mm) and may have crimped/sealed primer pockets. OFB may have slight imperfections such as minor dings, dents, or bent mouths. Most flaws can be easily removed during resizing. What cannot be removed during resizing may be removed upon your first firing.
ALL BRASS, new and once fired, must be thoroughly inspected and resized. Inspect product for correct caliber and primer size, as incorrect caliber or “bad” brass will ship occasionally. Additionally, any brass, new or once fired, should always be carefully inspected, and resized/decapped WITH YOUR DIES prior to loading. You will still need to FULL LENGTH RESIZE prior to loading.
