A friend has a Dumoulin Mauser in 7x57 that he has offered to me after the season. I believe it is an older one, but I don't know. It has the 3 position safety on the bolt and a 2 position safety above the trigger guard for scope use. He bought some Hornady Light Magnum loads for it and I was wondering if it is a gun that can handle modern pressure loads or should it be only shot with lighter pressure loads?

What is your opinion of these rifles?
