LAPUA BRASS .223
LAPUA manufactures its world-leading cases from the highest-quality raw materials and with superior smelting and metallurgical expertise. As a result, these cases maintain exact tolerances over multiple reloading cycles.
The bases of the cases are hard and resilient and therefore maintain their shape between reloads and prevent jamming in the cartridge chamber. Also, the necks of the cases are absolutely symmetric and annealed.
Their bluish colour is not an indication of poor finishing, but a LAPUA trademark: the mouth and neck will not crack even in multiple reloading.
