Chemical Composition
Elemental breakdown by percentage weight.
Standard composition limits
Values represent maximum allowed percentage unless otherwise noted.
Physical Properties
Material form, density, and contamination specifications.
Fired ammunition casings from shooting ranges, military training, civilian shooting sports; post-firing condition with combustion residue; established ammunition recycling stream; safety-critical material
Acceptable Inclusions
- Gunpowder residue and combustion byproducts
- Fired primer residue (copper/brass/steel)
- Dirt and dust from shooting range environment
- Corrosion from storage and age
- Brown/black oxidation from firing
- Moisture and environmental exposure
- Lead <2.5% (casing base limit; surface lead acceptable if not excessive)
- Mixed caliber casings in same lot
Prohibited Materials
- LIVE/UNFIRED AMMUNITION (EXPLOSIVE HAZARD)
- Active explosive residues (unburned powder concern - distinguish from normal residue)
- Copper content <70% (must be brass ammunition range)
- Significant bullet/projectile material (lead/steel contamination)
- Non-ammunition metal casings (wrong material)
- PCB or electronic components
- Radioactive materials
- Hazardous chemical contamination (beyond gunpowder residue)
- Unknown or unidentifiable material

Required Test Methods
Visual Inspection - Live Ammunition Screening
CRITICAL
Purpose
- confirm 100% of sample are FIRED/SPENT casings
- ZERO live/unfired ammunition
- NO intact primers or unburned powder
Acceptance Criteria
- All casings demonstrably fired/spent
- NO live rounds visible
- NO unexploded primers
- NO unburned powder
- casings empty or with residual burned primer only
Procedure
- 100% visual scan of ALL sample casings
- visual for firing marks, dents, primer pocket examination, corrosion indicating age/firing
- compare suspected live vs. fired characteristics
- ANY live round triggers full lot rejection
Firing Verification
CRITICAL
Purpose
- confirm casings are spent/fired (characteristic marks present)
Acceptance Criteria
- Firing dents visible
- primer pocket indentations clear
- case expansion evident
- no intact projectiles
- characteristic fired appearance confirmed
Procedure
- Detailed visual inspection for firing signs
- compare to reference fired casings
- examine primer seats for indentation
- confirm projectile absence
Material Type Identification
Purpose
- Confirm BRASS ammunition casings (NOT steel or aluminum)
Acceptance Criteria
- Brass/copper coloration evident (golden/reddish appearance)
- material consistency with ammunition-grade brass
Magnetic Test
Purpose
- Exclude steel casings or ferrous contamination
- verify brass non-magnetic character
Acceptance Criteria
- Non-magnetic or very weak magnetism (brass/copper expected)
- NO strong ferrous response
Procedure
- Magnet test on sample casings
- strong attraction indicates steel casing mixing (rejection trigger)
Powder Residue Assessment
CRITICAL
Purpose
- distinguish normal gunpowder residue from unburned explosive powder (safety hazard)
Acceptance Criteria
- Normal brown/black gunpowder residue visible (expected post-firing)
- NO unburned powder or fresh explosive material
- no atypical residue
Lead Assessment
Purpose
- Evaluate lead content (<2.5% acceptable)
- assess surface vs. core lead contamination
Acceptance Criteria
- Lead <2.5% by
- acceptable ammunition-grade lead content
- surface lead contamination documented if >1.5%
XRF Spectrometry
Purpose
- Verify Cu 70-85% and Zn 12-25% ammunition-grade composition
- assess lead (<2.5%)
- identify contamination
Acceptance Criteria
- Cu 70-85%, Zn 12-25% (ammunition-grade brass confirmed), Pb <2.5%, Fe <1.0%
Ammunition Type Identification
Purpose
- Identify ammunition type(s)
- assess caliber diversity if mixed lot
Acceptance Criteria
- Ammunition types identified
- caliber range documented
- mixed lots clearly characterized
Procedure
- Visual caliber assessment
- dimension measurement if uncertain
- document primary types and percentage representation
