History of the 7mm Remington Magnum

[JDT]

Is the 7mm Remington Magnum based on a shortened, blown-out, and necked down .300 H&H Magnum? If so, could 7mm Remington Magnum cases be re-formed to create .264 Winchester Magnum cases and vice-versa?

I don't know about the origins but you can make one out of the other or is that vise versa??

Yes all Winchester,Weatherby,& Remington belted magnums all trace their roots to the H&H magnums

It's actually based on a necked down 338 win. case.

That ls true,but they are all either full lenght improved or shortend H&H cases
