308...A 7.62mm = .300
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 parent case of the .270 is the .30-06, necked down. The parent case of the .243 is the .308 Winchester, necked down. Aside from the larger diameter of the .270, the .270 has a longer case.
If you are asking about the the cartridge length,then the 300 win mag.is longer than the .308win.caliber.If you are asking about bullet diameter then both cartridges are the same .308 bullet diameter.If you are asking about muzzle energy(hence power) then the 300 win mag.is considerably more powerful than the .308 winchester cartridge.
Negative, 308 is a 30 caliber bullet and 30 doesn't fit into 25.

A .308 bullet is a rimless and bottlenecked rifle cartridge. It has an effective range of around 500 feet if the shooter is good enough.
Sorry, you need to specify WHICH .308 bullet and at what distance. As distance increases, the RATE of drop also increases.
No, it does not.
No they are not. 7.62mm = .300
A 150 grain bullet shot from a 308 will start dropping the fraction of a second it leaves the barrel.
