280 ACK Peterson raw brass cases, once fired, suitable for reloading applications. These cases have been fired a single time for test purposes. Each case retains its original raw finish, with no polishing or post-processing performed. The brass remains in its fired state, providing a foundation for reloaders who prefer to perform their own cleaning, sizing, and preparation steps. This lot represents a consistent source of fired cartridge cases in the 280 ACK chambering.

All cases have undergone magnetic screening to remove any ferrous debris and have been machine sorted to ensure uniformity in dimensions and headstamp. Each piece has been hand inspected for structural integrity and suitability for reuse. The brass was originally fired by a firearms manufacturer during production test firing of new rifles, resulting in clean, single-use cases. This brass is used and maintains the natural fired coloration and surface characteristics typical of unprocessed cartridge cases.

The lot consists solely of 280 ACK raw brass cases, once fired, with no additional components or accessories included. The cases are unpolished and unprocessed, ready for full preparation by the reloader. This brass provides a starting point for those seeking control over their own reconditioning and load development processes.
