Those Mysterious Forty-fives

Ed is pretty good at that "facecious" stuff!

Postino, I agree that according to the chart the case length is different, as is the size of the extraction groove... but what about overall diameter of the case at the case head, and the mouth? angle of the case taper? What is the standard bullet diameter? .452" ?

If an SAAMI specification .45 ACP loaded round is inserted into a 1906 specification dimensioned chamber will it drop into the chamber with excessive headspace from the base to the breechface?

or will it likely stop based on case taper close enough for the breech to allow the extractor to work? and close enough for the firing pin to enable cartridge ignition?
