Yes it does, and the dimensions don't match your statement -

1mm longer than the .45 ACP would be .938" (using .898" as case length for the .45 ACP) which is not the same as the .918" shown in the table...

...Which is why I asked...I don't believe everything I read on the Internet (much less in Wikipedia) unless I see it multiple times and it is discussed in length...

Which is not to imply that I don't believe what you've written...I'd just like to see/know where you got it from...

(For instance, you may have read it in COTW - a book which I don't have...and I would believe that over the Internet site "45 Auto Cartridge History"...)
