Flattened Brass Bullet Casings & Stamping Blanks

Flattened Brass Bullet Casings — Ready-Made Blanks for Metal Stamping, Engraving & Etching

Genuine once-fired brass bullet casings, flattened into smooth, work-ready blanks — ready for metal stamping, laser engraving, hand engraving, and etching without additional prep. Each blank carries the authentic brass patina of a real fired casing. Available in multiple calibers, with and without pre-drilled holes for pendant and keychain work. Completely inert — no gunpowder, no live primer. Free shipping on every order.

Why Bullet Casing Blanks?
  • Authentic brass: each blank comes from a genuine once-fired casing — real brass, real firing history, not manufactured sheet metal.
  • Pre-flattened: each casing is individually flattened — the result is a smooth, work-ready brass blank with authentic once-fired character.
  • Ready to use: no additional prep needed — stamp, engrave, or etch directly onto the flat surface.
Popular Uses
  • Metal Stamping: ImpressArt and similar stamp sets work cleanly on the brass surface — names, dates, coordinates, short messages.
  • Hand Engraving: the brass surface takes a graver cleanly — ideal for custom memorial pieces, military tribute jewelry, and personalized gifts.
  • Laser Engraving: consistent flat surface and authentic brass color make these ideal for laser-engraved pendants, keychains, and tags.
  • Etching: the brass surface accepts ferric chloride and salt-water etching processes — for detailed artistic work and pattern transfer.
  • Resin Inlay: flatten, etch a design, fill with colored resin — popular technique for custom jewelry and art pieces.
FAQs

What calibers are available? Browse the collection — we carry multiple calibers including 9mm, .45 ACP, .223/5.56, .308, and shotgun shell slices. Each caliber produces a different blank size — 9mm is small and delicate, .308 is large and substantial.

Is bullet brass harder to stamp than craft store blanks? Bullet brass stamps beautifully — it simply requires a slightly more decisive strike than the softer metals most beginners start with. Here’s where it falls in the hardness spectrum:

  • Aluminum — softest common stamping metal; leaves deep impressions with minimal force
  • Copper — highly malleable; the standard baseline metal for beginners
  • Pewter / Alkeme — engineered specifically for effortless, light-tap stamping
  • Sterling Silver — softer and more forgiving than brass
  • Cartridge Brass — firmer than all of the above, but still a relatively soft, workable metal

Cartridge brass is a copper-zinc alloy that becomes slightly work-hardened during the manufacturing and firing process. The result is a blank that holds impressions exceptionally well once struck — deeper, crisper, and more durable than softer metals. A steel bench block underneath the blank and a single confident hammer strike is all it takes. If you’re used to stamping copper, just hit a little harder and you’ll get excellent results.

Are these compatible with ImpressArt stamps? Yes — ImpressArt letter and design stamps work on these blanks. Use a steel bench block, position the stamp carefully, and strike with a single firm blow. For larger stamps with more surface area, you may need to rock and re-strike to get full impression depth across the design.

Do you offer pre-drilled options? Yes — several listings include a pre-drilled hole for jump rings, cord, and chain. Check individual listings for availability.

What’s the difference between stamping, engraving, and etching on these blanks? Stamping uses a steel punch and hammer to press a design into the brass surface — fast, no chemicals, beginner-friendly. Engraving uses a graver or rotary tool to cut the design — more detail possible, steeper learning curve. Etching uses ferric chloride or salt-water electrolysis to chemically remove brass in a pattern — great for fine line work and tonal designs. All three techniques work on these blanks.
