.308 Winchester Once-Fired Brass for Reloading
Our once-fired .308 Winchester brass is sourced from range-fired ammunition, then sorted, cleaned, polished, inspected, and packaged for resale to reloaders.
Most of our standard mixed .308 Winchester brass consists of commercial headstamps, although military headstamps may occasionally appear depending on the source and composition of each batch. Lake City .308 / 7.62x51mm NATO brass is separated and sold as its own product option when available.
Most .308 Winchester brass uses Boxer primer pockets and Large Rifle primers. However, some manufacturers produce .308 Winchester cases with Small Rifle primer pockets. Reloaders should always inspect each case and verify primer pocket size before reloading.
Available product options may include Washed & Polished, Nickel-Plated, Lake City, Berdan-primed cases, or dirty steel casings when available. Please review each individual product title and description before ordering.
Most once-fired brass orders include approximately 2–3% additional brass. Once-fired brass is a previously used product, and while we work hard to maintain high quality standards, no inspection process is perfect. We also recognize that every reloader's inspection standards and intended use may differ. Please see our Brass Information page for details regarding our overpack policy.

Quality Standards & Processing (Click to expand)
How We Process .308 Winchester Brass
Our .308 Winchester brass passes through multiple stages of mechanical sorting, cleaning, polishing, and hand inspection before being packaged for sale.
Incoming brass is first processed to remove loose debris and obvious contaminants. It is then sorted using a combination of specialized equipment designed to separate brass by material, body diameter, rim diameter, and case length. Depending on the caliber and sorting group, additional processing steps may be used to improve sorting accuracy.
Most of our brass is then wet washed, rinsed, and finished in heated corncob media to improve appearance while helping preserve the brass during storage.
After cleaning, every batch is hand-inspected. During this process we remove cases showing split necks, severe corrosion, major physical damage, severely damaged rims, excessive discoloration, or other conditions that could affect reloadability.
Our Quality Standard
Once-fired brass is a previously used product, and every case has its own history. While no inspection process can identify every possible defect, our goal is to provide brass that we would be confident using ourselves.
Many inspection decisions rely on practical reloading experience rather than a simple checklist. If a case does not meet the quality standard we expect for our own reloading bench, we would rather remove it than ship it.
Regardless of where your brass is purchased, every reloader should thoroughly inspect every case before reloading. This is one of the most important steps in producing safe, reliable ammunition. While we work hard to identify and remove defective cases, once-fired brass is a previously used product and no inspection process can guarantee that every defect will be found. The final inspection should always be performed by the individual assembling the ammunition.
Most once-fired brass orders include approximately 2–3% additional brass. While this helps compensate for the occasional case that may not meet our quality standards or your individual expectations, it should never replace a careful inspection before loading.

Preparing .308 Winchester Brass for Reloading
Proper case preparation is an important part of producing safe, reliable, and consistent ammunition. While every reloader develops their own routine, inspecting, resizing, measuring, and preparing each case before loading is considered standard practice.
.308 Winchester vs. 7.62x51mm NATO Brass
Although .308 Winchester and 7.62x51mm NATO share nearly identical external dimensions, there are differences that reloaders should understand before developing loads.
- Military 7.62 NATO brass often has thicker case walls than commercial .308 Winchester brass.
- Reduced internal case capacity may affect pressure when using the same powder charge.
- Many military cases have crimped primer pockets that require swaging or reaming before a new primer can be seated.
- Case capacity, brass hardness, and primer pocket construction vary by manufacturer and headstamp.
- Whenever changing brass manufacturers or switching between military and commercial case types, begin with published starting loads and work up carefully.
Case Length and Trimming
Like most bottleneck rifle cartridges, .308 Winchester brass tends to lengthen during firing and resizing. Cases should be measured periodically and trimmed as necessary to remain within published specifications.
Many reloaders trim cases to approximately 2.005 inches to maintain consistency, although every case should be measured before trimming.
Primer Pocket Inspection
Most .308 Winchester brass uses Large Rifle primers, although some manufacturers produce cases with Small Rifle primer pockets. Mixed-headstamp brass should always be checked before priming.
Military 7.62 NATO brass—including Lake City cases—may contain primer crimps that must be removed before seating a new primer.
Headstamp Sorting
Our standard .308 Winchester brass is sold as mixed headstamp unless otherwise specified. Many reloaders successfully use mixed brass for general shooting and hunting. Precision shooters often choose to sort cases by headstamp, case weight, or lot number to improve loading consistency.
Case Life
The useful life of .308 Winchester brass depends on factors such as chamber dimensions, load pressure, resizing practices, and overall case condition. Every case should be inspected before each loading and discarded if signs of failure or excessive wear are present.
Annealing
Some reloaders choose to anneal bottleneck rifle brass to help maintain consistent neck tension over multiple reloadings. Annealing is optional and should only be performed using proper equipment and accepted procedures.

About the .308 Winchester Cartridge
Introduced commercially in 1952, the .308 Winchester quickly established itself as one of the most successful rifle cartridges ever developed. Its excellent balance of accuracy, manageable recoil, and versatility has made it a favorite among hunters, competitive shooters, military marksmen, law enforcement agencies, and recreational reloaders.
The military counterpart to the .308 Winchester is the 7.62x51mm NATO cartridge. While closely related, reloaders should understand the differences between commercial and military brass before developing loads.
Common Firearms Chambered in .308 Winchester
.308 Winchester is chambered in a wide variety of rifles, including:
- Bolt-action hunting rifles
- Precision and long-range rifles
- AR-10 / LR-308 style rifles
- M1A rifles
- FN SCAR 17 rifles
- Numerous sporting and tactical rifle platforms
Commercial and Military Brass
Our standard .308 Winchester brass is sold as mixed headstamp unless otherwise specified. Depending on the source of each batch, customers may receive commercial and occasional military headstamps. Lake City brass is separated and sold as its own product whenever practical.
Military brass often contains primer pocket crimps and may have slightly different internal capacity than commercial brass. These differences are normal and should be considered during case preparation and load development.
Nickel-Plated Brass
Nickel-plated .308 Winchester brass is occasionally available as a separate product option. Many reloaders appreciate nickel-plated cases for their corrosion resistance, ease of identification, and attractive appearance. Availability varies considerably depending on the brass received from our suppliers.
Berdan-Primed Brass
Most reloaders in the United States use Boxer-primed brass because it is compatible with standard reloading equipment. Berdan-primed .308 brass requires specialized tools and components and is offered separately whenever available.
Steel Cases
Steel-cased .308 / 7.62 ammunition is occasionally encountered during sorting. When available, steel cases are offered separately and clearly identified. Steel cases should not be confused with reloadable Boxer-primed brass.
