The 7×33mm Sako cartridge was created in Finland in 1942 as a small game cartridge for animals such as the Capercaillie and Black Grouse. It is based on a 9×19mm Parabellum case that has been lengthened and necked down to accept a 7.21mm bullet. The cartridge overall length is 44.30mm with a case length of 33.30mm and a base diameter of 10mm. The bottleneck
