7.62x39 brass

Lapua’s 7.62×39 brass is renowned for its exceptional quality, benefiting from top-tier raw materials and advanced manufacturing techniques. The company adheres to stringent quality control measures throughout production to ensure each piece of brass meets high standards for hardness, durability, and grain structure. In line with the Commission Internationale Permanente's standards, Lapua brass undergoes rigorous testing at 30% overpressure, though it's important to note that this applies to the brass itself, not the loaded ammunition. During the brass preparation phase, minor imperfections may sometimes be noticeable, especially with bulk rifle brass. These can include case mouths that appear slightly out of round or minor dents below the shoulder, often resulting from the final tumbling wash after annealing. While manufacturers strive to minimize these cosmetic issues, some imperfections can occur due to the design of the equipment. Fortunately, these small dents generally do not affect the brass's overall performance or lifespan and are often resolved during the initial firing. Non-plated brass may also show anneal stains, which can give the case neck a faint pinkish hue. These are merely superficial and do not impact the brass's functional quality. For smaller caliber cases, slight bellying of the case mouths might be observed. This is a normal part of the manufacturing process and does not affect performance. Understanding these minor imperfections can help set realistic expectations and ensure the brass remains reliable despite any visual variations.
