As raw material prices continue to surge globally, Shell Shock Technologies (SST) is keeping a close eye on the forces reshaping the economics of ammunition manufacturing—particularly when it comes to large-caliber rounds like the 7.62x51mm. One of the most pressing developments is the sharp increase in copper prices, which is directly impacting the cost and availability of traditional brass-cased ammunition.
An internal analysis by SST’s Lead Engineer, Anthony Viggiano, highlights just how significantly these changes will affect the market. With copper demand driven by expanding data center infrastructure, renewable energy projects, and transportation electrification, the traditional materials used in ammunition production are becoming increasingly costly—and less reliable.
Brass, the traditional material used in ammunition casings, is composed of 70% copper and 30% zinc—a formulation known as cartridge brass (C26000) that has long been favored for its durability and workability (Austral Wright Metals).
However, the economics of sourcing and producing brass are changing rapidly. The United States currently imports approximately 45–60% of its refined copper, leaving domestic markets vulnerable to global supply chain shocks and policy shifts. Recently, the announcement of a proposed 50% tariff on imported copper—set to take effect August 1, 2025—has already begun to send copper prices surging. Copper futures jumped as much as 13%, with U.S. prices projected to climb to $8.50/lb. or higher in the coming months (Wall Street Journal, Investopedia).
When combined with zinc—currently priced at around $1.24/lb.—the projected blended cost of cartridge brass rises to approximately $6.63/lb., or $0.0146 per gram.
To put that in perspective: a standard 7.62x51mm Lake City brass case contains approximately 14.2 grams of brass. At today’s spot prices, this equates to $0.207 in raw material cost per case—before factoring in any additional expenses for forming, tooling, or assembly. Just a month prior, the same case cost only $0.112, reflecting a staggering 46% increase in base material cost.
These increases aren’t theoretical—they represent a real and growing challenge to ammunition manufacturers who rely on brass casings. The combination of tariff-driven copper inflation and constrained supply chains is likely to drive both cost increases and volatility in the production of traditional brass-cased ammunition in the months ahead.
Shell Shock Technologies offers a modern alternative to this looming crisis. The company’s proprietary NAS³ case technology is manufactured from a nickel-stainless alloy rather than traditional brass. This material not only avoids the volatility of copper and zinc pricing, but it also requires a fraction of the raw material mass compared to brass equivalents—further lowering the cost and improving sustainability.
Additionally, NAS³ cases offer several performance advantages, including greater strength, lighter weight, and improved corrosion resistance. The design also enables the use of SST’s innovative two-piece construction, which enhances reliability and extends case life.
SST recently launched full production of its NAS³ 7.62x51mm round, and early demand has exceeded expectations. The initial production run sold out within 24 hours, signaling both domestic and international interest in an alternative that is both high-performing and economically stable. As a result, the company is actively evaluating options to scale manufacturing capacity to meet rising market demand.
For those interested in seeing the round in action, a test fire video conducted by Regional Operations showcases the 7.62x51mm/.308 NAS³ round’s performance and reliability under live conditions.
As market dynamics shift, ammunition manufacturers, commercial users, and military suppliers alike must prepare for ongoing cost increases and sourcing uncertainty tied to traditional brass casings. Shell Shock Technologies remains committed to delivering innovative, forward-looking solutions that mitigate supply chain risks while improving performance across the board.For more information about the NAS³ 7.62x51mm round, contact Shell Shock Technologies at www.shellshocktech.com.
