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.
If it is still original they are very well made and quite accurate. Low recoil makes them fun to shoot. The 6.5 X 55 mm cartridge is common among European target shooters and hunters.
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.
Here is an inexpenive and effective deer feeder I made recently.
No batteries to go dead, no hoisting it up in the tree, plenty of capacity, very easy to fill - so far, I love it.
I have made two of these and they are easy to build.
An empty 55 gallon drum, some 2x4's, some PVC tubing and fittings, a little bit of hardware and some paint - and you are ready to go.
I designed it so you can stand on the lower rung and fill it - the top is about 6.5 feet above the ground.
It holds about 375...
