The Sweds NEVER built 1898 style military Mauser actions. Sweds made small ring pre-1898 style actions during their entire production run, 1894+/- through 1942/43. When Husqvarna built sporting rifles on large ring actions after WW2, they imported them from FN in Belgium.
I think that you are over-reaching, reading things into this that just aren't there.
There might be another explanation. In the early 1930's, the Swedes adopted the 8X63mm (M32) cartridge for machine gun use. They similarly adopted the M98 Mauser chambered for the same cartridge to be issued to machine gun troops; the reason being that the troops could always use the machine gun rounds and thus simplify logistics. These rifles were manufactured in and purchased from Germany.
Recoil was pretty severe (according to one man I met in Sweden) and the rifles were despised. In the 1970's these rifles were re-barreled for the 7.62X51mm NATO.
It is conceivable that these German made M98's were stamped with the Swedish crown after acceptance.
