Genuine once-fired .40 Smith & Wesson brass shell casings — recovered from real firing use, cleaned and individually inspected.

This collection includes empty brass and nickel casings, pre-drilled casings ready for jewelry findings, deprimed casings with a clean primer pocket, and thin-cut bullet slices in brass and nickel. Every piece is completely inert — no gunpowder, no live primer. Free shipping on every order.

Popular Uses
  • Bullet Jewelry: the .40 S&W casing has a wide, flat base — distinctive in earrings, pendants, and keychains, especially in nickel finish.
  • Brass Bullet Slices & Nickel Bullet Slices: thin cross-sections of the .40 S&W casing — ideal for earring settings, pendant bezels, and mixed-media inlay work. Available with and without primer.
  • Pre-Drilled Casings: hole already drilled for jewelry findings, cord, and chain — ready to string without additional tools.
  • Deprimed Casings: primer removed for a clean, open primer pocket — preferred for resin filling, setting stones, or any project where primer presence matters.
  • Resin Art: the broad diameter embeds cleanly in coasters, paperweights, and tabletop pours.

FAQs

Are these the same as .40 cal casings? Yes — .40 S&W, .40 cal, and .40 Smith & Wesson all refer to the same cartridge. The full name is .40 Smith & Wesson, commonly shortened to .40 S&W or .40 cal.

Is .40 S&W the same as 10mm? No — they’re related but different. The .40 S&W was developed as a shorter version of the 10mm Auto for use in standard-frame pistols. The external case diameter is similar but the 10mm is longer. They are not interchangeable.

Are these safe to handle? Yes — completely inert. Once-fired, spent, no gunpowder or live primer. Craft and display use only.

What finishes are available? Brass (standard gold tone), nickel (bright silver), steel (darker, magnetic), and aluminum — availability varies by listing. Browse the collection for current stock.
