I was reading through older threads when I came across this one: .308 is ballistic twin of 8mm mauser

I was confused as I remember that the original loads for 8mm were closer to the 30-06 in terms of velocity and muzzle energy, but have been watered down for older rifles by most ammo factorys to the point they are the same as 7mm Mauser.

Then another person commented that the .308 was derived from the Frenchicon 7.5mm round.

That is the first time I had ever heard that. Is this true?

I was curious as I had always read/heard that the .308 was derived from the .300Savage round, but with a neck and shoulder that was better for automatic weapons: and was designed to duplicate WW I 30-06 power in a short action.

This also seems more plausible to me as the .300savage was developed 4 years before the 7.5mm French round.

However, I am NOT an expert. I just would appreciate some clarification.

Thanks!
