So if I am not mistaken, the model 46's were on Swedish small ring actions. The model 146 and 246 rifles used the Belgian FN older style 98 action. And the 640 series of rifles used the Swedish small ring as well as Belgian FN 98 older and newer style actions. As far as the rifles that were chambered in 9.3x57mm you will see the ones with the squared off pistol grip and Schnabel forend configuration with large ring 98 and small ring 94 actions both. The 9.3x57mm rifles with a bag type pistol grip and rounded forend I think they were all 94 Swedish small ring actions. Hopefully someone else can chime in with more information.
