What is Once Fired Brass?

Once Fired Brass (OFB) is NOT NEW brass, it is an ammunition/firearms industry term to loosely describe used reloading brass cases. If looking for a perfect case, better to purchase new brass cases. Although called “once” fired, the actual number of times fired is unknown. We have serviced indoor, law enforcement (LEO) and military ranges, and contrary to popular opinion from our competitors and some reloaders, they all have brass that has been shot more than once (regardless of their policies and rules). Therefore, we never claim our brass has been shot only once, we know better.

  • Our range brass includes commercial and military casings. We do not sort by headstamp, manufacturer, case length, flash hole size or primer size, unless specifically stated.
  • Brass purchases are for an 'As Is' condition. We do not warrant these for every possible use and bullet combination, they are for general reloading in a multitude of guns. Some also may be deprimed, regardless of our stock photos. If they are damaged and can't be used, we will replace them, with the exception of bulk dirty brass.
  • OFB may have imperfections, such as minor dings, dents, or bent mouths. Most flaws can be easily removed during resizing or upon first firing. This does not mean they are unusable, it just means you most resize them and fire them to remove the dings. Click here to learn more.
  • Brass casings come with several different primer flash hole sizes,  .057 small flash hole, .074 (standard size) and .110 (50 BMG). Ensure you have the correct decapping pin when resizing/decapping as there is not a standard and manufacturers can use any size they want.
  • Additionally, there is not a standard for primer sizes in cases, manufactures can and do, use different sized primers in their products. Note, Federal has both large and small 45 ACP, as does Starline for their 6.5 CM, and many others do the same.

Inspect All Brass

  • ALL brass must be thoroughly inspected and resized. Inspect product for correct caliber and primer size, as incorrect caliber or “bad” brass may ship occasionally.
  • Carefully inspect and resized/decap brass WITH YOUR DIES prior to loading. You will need to FULL LENGTH RESIZE prior to loading. Accurate reloading is based upon consistency, if you don't reize your brass with your dies prior to reloading, then they are not consistent, and your accuracy will suffer. US Reloading Supply is not liable for damage to your equipment or weapon under any circumstances.
  • Some brass sizes may include CRIMPED PRIMERS. When working with crimped cases, care must be given to ensure the primers are removed correctly and swaged. If you do not understand the difference between these types of cases, please contact us for information prior to ordering.
