Sako L42

About the Sako L42

The Sako L42 (Luodikko malli 1942) was the first civilian bolt-action rifle to bear the Sako name, developed in wartime Finland in 1942. It was designed around the purpose-built 7x33mm Sako cartridge, a small-game round intended for capercaillie, black grouse and similar game. Only a handful of prototype rifles were made before Finland's continued involvement in the Second World War halted development; the design was never mass-produced and instead evolved into the postwar Sako L46 micro-action sporter introduced in 1946.

The 7x33mm Sako cartridge created for the L42 was ingeniously built from a lengthened, necked-down 9x19mm Parabellum pistol case, turning surplus wartime brass geometry into a flat-shooting small-game rifle round.

Sako L42 specifications

The L designation comes from the Finnish word 'luodikko' (rifle). Because development was repeatedly interrupted by the war and never satisfied its own designers, the L42 remained a prototype. Detailed physical dimensions (barrel length, weight, overall length) are not reliably documented for the surviving prototypes.
