The 6.5x47mm Lapua Brass Cases have been designed to maintain exact tolerances over multiple reloading cycles. Advanced metallurgical research and manufacturing techniques ensure that Lapua cases are leaders in uniformity and quality. The Lapua case heads are drawn exceptionally hard for unmatched reloadability and for an exceptionally long life cycle to serve top shooters time and time again. The brass dimensions remain constant and will hold primers tight in their pockets even after many reloadings. The brass body section of Lapua cases is hard and resilient for unmatched durability. It is easy to extract after firing, whether the reloader opts for full sizing or neck sizing only. Strict tolerances in concentrity and wall thickness are used in manufacturing of the case neck. The neck and shoulder of Lapua cases are annealed to withstand repeated reloading. Lapua cases are the best in the world, a statement supported by all top marksmen. Lapua brass is manufactured to be reloaded, again and again
