In all reality, the cartridges are almost even. When both are using heavy bullets (about 200 grains), they tie. when using lighter bullets (150 grains), the 30-06 outclasses the 7.92x57mm because the bullet can move faster and not drop as much. For hunting purposes, I would stick with a 30-06 (Even though I own a 7.92x57mm Rifle) because you have more options with bullet weights.
Need much more information.
It means the action of the rifle was made by Mauser or copied by someone.
I'm not quite sure about the 3006, but I know that the longest recorded kill shot with a .308 was at about one and a half miles, possibly more.
Define 7mm. Do you mean 7mm Mauser ( a little less than 30-06), or 7mm Magnum, (a bit more than 30-06)
