The .308 has a shorter cartridge case, and a fatter bullet. The .270 is based on the 30-06 case, about a quarter inch longer than the .308 case.
The E model was an economy model made from 60-84
The .30-06 is 12mm longer, and has a flatter trajectory.
The .50 caliber is larger in diameter than the .308. If you are referring to the bullets for the .50 BMG and the .308 Winchester, the .50 is MUCH heavier, and much longer than the .308.
Neck angles, headspacing, pressure generated by the cartridge when fired.

The .308 Winchester and the 7.62 NATO cartridges are similar in size, but slightly different in chambering, thickness of the cartridge case, and pressures in loading. The 7.62 NATO cartridge may be safely fired in a .308 Winchester firearm. The reverse is not always true.
