Trying to wrap my head around this round, the 45 S&W Special, aka 45 Frankford.

From kcwheel we learned the chamber specifies as measured in his revolver.

Cylinder OD: 1.694
Clinder length: 1.580 (1917 cylinder is 1.535
chamber depth: .895
Chamber dia: .477
Throat dia of cyl: .454
The front of the chamber is tapered like any other rimmed cartridge chamber.

I will try to attach some pictures. The third round has no headstamp, all others have the FA 4 06.

From Honda44, we are reminded of the similar 45 Cowboy Special.

Am I seeing it correctly, the the S&W Special is the length of the Cowboy Special plus the thickness of the rim? The CS is the length of the depth of the S&W Special chamber?

Somewhere in this thread, someone must have posted a case length for the S&W Special cartridge and I have missed it!
