I received this rifle, a 8x57 SJ Mauser as a gift from a friend, he bought it 25 years ago and used it once, I would like to revamp it and use it to hunt with...please be so kind as to advise me on the strategy I should follow to fulfill this wish. If possible tell me more about this weapon and the ammunition it requires. I would further more like to come in contact with an owner of the same caliber weapon as mentioned.
