Brass, Grade Information
Shell Cases
Spent brass cartridge and artillery shell cases, a distinctive and consistent scrap grade from military ranges, shooting clubs, and decommissioned military stores.

History & Interesting Facts
The metallic cartridge case was developed in the 1840s and 1850s, revolutionising firearms design. Before cartridge brass, firearms used separate powder, ball, and percussion cap, a slow and moisture-sensitive loading system. The Flobert cartridge (1845) and subsequent rimfire and centrefire designs used brass because of its unique ability to withstand and then spring back from the enormous pressure of firing (this property is called "obturation"), sealing the chamber against gas leakage. The composition of cartridge brass, 70% copper, 30% zinc, was established empirically and has remained largely unchanged for 170 years because no other economical material matches its combination of deep-drawability, strength, corrosion resistance, and spring-back properties. Britain's Royal Arsenal at Woolwich produced millions of brass cases annually through both World Wars. Spent cases from military ranges, shooting clubs, and decommissioned ammunition stores have been scrap traded for as long as metallic cartridges have existed.
Historical Uses
Cartridge brass, 70/30 Cu-Zn, has been the universal material for small arms and artillery cartridge cases since the 1860s. Its applications span the entire range of ammunition, from .22 rimfire to 120mm tank rounds. Shell cases serve the critical function of containing the propellant charge, sealing the chamber during firing, and ejecting cleanly after discharge. Military campaigns of the 19th and 20th centuries produced staggering quantities of spent cases, Crimea, the Boer War, WWI and WWII all generated spent brass that was systematically collected and reloaded or scrapped for the war effort. The term "brass" as military slang for senior officers comes from their polished brass insignia, itself a reflection of how central brass was to military culture. Civilian shooting sports (target shooting, game shooting) generate smaller but consistent quantities of spent brass, often hand-loaded by shooters before eventually reaching the scrap stream.
Current Uses
Shell cases in the UK scrap market come primarily from military training ranges (MoD authorised disposal of spent cases after firing), civilian shooting ranges and clubs, decommissioned military ammunition where cases are separated from live components, and occasionally collector disposal of inert display items. All shell case purchases require appropriate due diligence, cases must be demonstrably inert (fired or deactivated), and dealers must comply with their obligations under the Scrap Metal Dealers Act 2013. Spent cases are recycled as cartridge brass or re-melted into general copper-zinc alloy. Some fired cases, particularly large-calibre artillery cases, are reloaded commercially, commanding higher value than scrap. The ongoing high tempo of military training and international defence commitments ensures a consistent stream of spent cases from MoD ranges.
Future Possible Uses
The global demand for ammunition, driven by military modernisation programmes, geopolitical tensions, and sustained civilian shooting markets, ensures that cartridge brass will remain a significant material flow for the foreseeable future. NATO countries' increased defence spending commitments following geopolitical events of 2022–2026 are directly increasing ammunition production volumes and therefore spent case generation from training. The development of new calibres and the gradual replacement of some brass cases with steel-cased ammunition in some military contexts may shift the composition of future scrap, but brass cases will remain dominant in high-performance rifle and pistol ammunition. Some ammunition manufacturers are actively working to develop fully biodegradable or recoverable training ammunition to reduce environmental impact on ranges, this could eventually modify the scrap stream but represents a long-term development.
Where Does This Scrap Come From?
Shell case scrap reaches scrap yards through authorised channels only. MoD Defence Equipment and Support (DE&S) periodically disposes of spent cases from military ranges through approved contractors. Civilian shooting clubs and ranges collect and periodically sell accumulated spent brass. Commercial ammunition reloaders sell cases that have reached the end of their useful reloading life. Collectors disposing of inert display ammunition must ensure cases are demonstrably fired or deactivated before sale. QuickStop Metals operates within the full requirements of the Scrap Metal Dealers Act 2013 for all ammunition-related scrap, full identity verification and proper documentation is required for all such transactions. Sellers should separate brass cases by calibre where possible, as large-calibre artillery brass pays differently from small-calibre rifle or pistol brass.
How Is It Remanufactured?
Spent shell cases are de-primed (spent primers removed) and cleaned before assessment. Those suitable for reloading are segregated and sold to commercial reloaders at a premium over scrap. Cases with neck or body cracks, excessive work-hardening, or other defects unsuitable for reloading are processed as brass scrap. Scrap cases are shredded or granulated and charged into a brass melting furnace. The 70/30 composition of cartridge brass is well-defined and makes it a high-quality feedstock for producing new cartridge brass sheet (for stamping new cases) or general yellow brass products. The processing cycle is well-established, wartime recycling of spent cases fed new ammunition production, a genuinely circular loop. Modern ammunition manufacturers including BAE Systems Global Combat Systems and Vista Outdoor use recycled brass extensively in new case production.
5-Year Price Trend & Forecast
Shell case scrap prices track yellow brass (70/30) market rates, typically paying slightly below clean plumbing brass at the scrap yard due to the processing required (de-priming, cleaning, and sorting). UK scrap prices for clean spent cases have ranged from approximately £2,600 to £4,600/tonne over the 2021–2026 period, tracking LME copper and zinc movements closely. Large-calibre artillery cases (which may weigh several kilograms each) are sometimes priced individually. The strong upturn in global ammunition demand from 2022 onward has tightened the market for secondary brass generally, supporting prices. Defence industry contacts suggest sustained high demand for brass scrap as ammunition production capacity is expanded across NATO member states in response to strategic stock rebuilding requirements.
