Cartridge cases are an important factor in this reputation. Superior quality ensures a long life and many reloads. Norma cases are made of the best possible raw materials and to the tightest tolerances; they deliver accuracy round after round.\u003c\/p\u003e\n\u003cp\u003eThe case neck is annealed to make it softer. This prevents gas leaks and enables the case to hold the bullet firmly for at least 10 years without cracking as a result of aging material.\u003c\/p\u003e\n\u003cp style=\"float: right;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0032\/7306\/4493\/files\/norma-cases-inside.png?3167\" style=\"float: right;\" width=\"300\" height=\"376\"\u003e\u003c\/p\u003e\n\u003cp\u003eFurther down on the case body, the hardness increases to avoid unnecessary stretching.

Here, the hardness is nearly twice that of around the case neck.\u003c\/p\u003e\n\u003cp\u003eThe structure of the material reveals the hardness. During processing the large, soft grains are broken down into smaller ones, which makes for a harder material. After the case under goes an annealing process, the smaller grain structure increases in size causing the hardness to decrease.\u003c\/p\u003e","brand":"NORMA","offers":[{"title":"Default Title","offer_id":29705108750381,"sku":"NORM-U21163","price":301.1,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0032\/7306\/4493\/products\/norma_20211631_470-NitroExp_1.jpg?v=1610220308","url":"https:\/\/www.reloadingsolutions.com\/products\/norma-brass-470-nitro-express-3-1-4-inch-unprimed-50-bag","provider":"Reloading Solutions Limited","version":"1.0","type":"link"}
