LAPUA GmbH
In 1829, the merchants Louis Sellier and Nicolaus Bellot founded a company for making percussion primers. In the 150 years to follow this company developed to a significant producer of ammunition and explosives. LAPUA OY, a Finnish enterprise, bought in 1992 the ammunition production in Schoene-beck. Under the guidance of the new owner the successful production of subcaliber, hunting and shot ammunition of the traditional SK brand could be further extended. Today, the LAPUA GmbH is one of the most important makers of
subcaliber ammunition. For many years, sport shooters, biathletes and hunters have put their trust in cartridges from Schoenebeck, which are especially known all over the world for their high precision, absolute reliability and perfect quality.
Wolf Match Target and SK Standard Plus are the same ammo made
on the same machines. The lighting makes the lubes look different but they are identical.
