The “B” denotes Birmingham production, while “C II” indicates the Cartridge Mark II specification—an early black powder loaded ball cartridge adopted in the late 1880s.\u003c\/p\u003e\n\u003cp\u003eThe Mark II cartridge was originally designed for use in the Lee-Metford rifle and represents one of the first standardised .303 British military loadings. These early black powder rounds predate the later cordite developments and reflect an important transitional period in British ammunition history.\u003c\/p\u003e\n\u003cp\u003eThis example has been professionally deactivated and is completely inert, making it safe for display (subject to local regulations). The brass casing displays honest age-related patina, with crisp and well-defined headstamp markings that enhance its authenticity and collector appeal.\u003c\/p\u003e","brand":"Tom \u0026 Jerrys Militaria and Collectables","offers":[{"title":"Default Title","offer_id":56786687721847,"sku":null,"price":22.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/9263\/6991\/files\/IMG_3495_8ee27732-dd50-4e4e-bc77-6924e9e1820e.jpg?v=1771884532","url":"https:\/\/tommies-militaria-and-collectables.myshopify.com\/products\/inert-303-british-b-c-ii-headstamp-cartridge-early-mark-ii-ball-round","provider":"Tom \u0026 Jerrys Militaria and Collectables","version":"1.0","type":"link"}
