An old Mauser re-chambered for a 30-06 case and the case necked out to .323 and you have an 8MM-06.
The larger bullet base gives more area to push on so I would think you get the same advantage the 32 Win Spcl has over the 30-30.
Typical load using a 150 gr bullet and 59 grains of 4895 gives you a muzzle velocity of 3026 fps and energy of 3050 ft/lbs.
Or you could borrow my .348 and see if you like getting your bell rung everytime you pull the trigger.
It's only a 150 yard gun practically speaking but it will stop a freight train...well a small train.
