The weight of one thousand 9mm cartridge cases depends on several factors, primarily the material (typically brass) and the specific manufacturer. Minor variations in case design can also contribute to weight differences. While a precise weight cannot be stated without specifying these factors, a common range is between 2.5 and 3.5 pounds (approximately 1.1 to 1.6 kilograms). This information is relevant to reloaders who purchase cases in bulk and need to estimate shipping costs or storage capacity.
Understanding the weight of spent brass is important for several reasons. For reloaders, knowing the approximate weight per thousand cases allows for accurate cost calculations when selling to scrap metal recyclers. This weight also factors into shipping costs, both for purchasing new or once-fired brass and for sending spent brass for recycling. Beyond the individual reloader, commercial ammunition manufacturers utilize this information for production planning and logistics. Historically, the weight of brass has influenced the economics of cartridge production and military logistics, particularly during wartime when brass was a strategic material.
