But the original question was about using one as a hunting rifle. I answered the OP's question on that basis, not on whether there are better rifles made today, or how much of an overload it would take to blow it up. The 7x57 is a perfectly adequate deer cartridge and a Spanish Mauser in that caliber and in decent shape can be a good and inexpensive hunting rifle.
Yes James. It's like teetering on a fence top. Has to be my imagination but as mentioned before, this rifle is begging to get out of the house to explore again. In reality, I would like to use/experience it in action. A modern 7x57 to me wouldn't be much different than a modern 270, only maybe more reliable. I say maybe because I don't use them that often. At my rate of use, this mauser would easily last another decade. So, the mauser can hang on a wall to be forgotten...I don't see that happening. Maybe I have to learn and decide the hard way as I'm sure many people have been down this road with these older guns. I haven't fired this one yet so I'm sill at point A.
