I know I am going to get some flak on this one, but the 8x57 Mauser will do practically anything the 30-06 will do. It is a good hunting cartridge, and probably more popular in Europe than North America.
While European hunters understand the differences in the 8x57 designations of the calibre, here in Canada and the USA, we seem to not comprehend what those letters after the 8x57 printed on the box mean. Originally, the 8x57 was made in .318 diameter bore size, but it was later changed to the more common today .323 bore size.
Because of the difference in bore sizes, and the possibility that someone will load a .323 diameter cartridge in an older rifle, (such as the 88 Mauser,) most North American ammunition is a bit underloaded and does not take full advantage of the cartridge. This is a "liability" factor on the part of the US ammunition manufacturers, but it you use some of the European ammunition, then it really shines.
As mentioned, Trade-ex has some great buys on 8x57 rifles. I would choose one of the Husqvarna "Commercial" actioned rifles, as it does not have the left side wall of the receiver notched out for clip loading. Possibly a bit stronger action, and certainly looking more like a sporting rifle rather than a converted military one. If you choose wisely, you could find one with a side safety, and receiver drilled and tapped for scope bases, thus saving a bit of money on gunsmithing.
