The Model 96 Swede is a small ring Mauser unlike the Model 98 which is a large ring. The smaller receiver ring somewhat limits the case pressure so consider that if you want to bubba it by rechambering to a super duper magnum.

As for yours, Carl Gustaf is a arms maker in Sweden. The 1917 is the year the receiver was made. Husqvarna (yes, the saw people) also made M-96 Mausers.
