When brands reference bullet fragments or similar sources, the underlying material is typically reclaimed metal (often brass, copper, or mixed alloys) that has been cleaned and reprocessed. The key challenge is verification: “bullet” provenance is a story claim, while the material needs composition clarity for accurate labeling. Where verified, this can represent meaningful reuse of recovered scrap; where unverified, it should be treated as “recycled mixed metals.” Recycled metals are used in jewelry and small hardware, prized for durability and infinite recyclability.
