When surplus Swedish Mausers became available after World War II many m/1896 and m/1938 rifles were successfully converted by Carl Gustafs and Norma into the CG 63 Competition/Target Rifle chambered in 6.5×55mm and 7.62×51mm NATO. A number of CG 63 match rifles were acquired by the Swedish Army, with their rifles colloquially known as "Gevär 6" if in 6.5×55mm and "Gevär 7" if in 7.62×51mm. These competition/target rifles were used by members of the Swedish Volunteer Sharpshooting Movement "Frivilliga Skytterörelsen" (FSR) and are known to be very accurate for their price. The FSR strived to keep the costs of participating in their shooting events reasonable, so the FSR rulings restricted the unchecked use of very expensive highly specialized target rifles, ammunition and other gear.
