Nosler uses only American brass cups for their cases. All Nosler cases are constructed from their high quality, specially formulated brass. Unlike their prepped brass, this un-prepped brass is not sorted by weight and no final trimming or sizing has been accomplished, though it is hand inspected to ensure each piece conforms to Nosler’s tight tolerances.
This high quality Nosler brass is ready for you to perform the final steps to your exact specification. When you complete the prep work, the brass is customized to your desired load. Note that brass should be full-length sized and trimmed to length before loading.
