7×33mm Sako

The 7x33mm 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 9x19mm 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 Bertram company of Australia makes brass for it.

Rifles chambered in this caliber include the Sako Models L42 and L46.
