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 7.21 mm (0.284 in) bullet.
The Bertram company of Australia makes brass for it.
Sako offers two loadings: a 78 gr (5.1 g) FMJ, and a 78 gr soft nose.
[2] Rifles chambered in this caliber include the Sako Models L42 and L46.
