From an earlier IAA Forum discussion, the so-called “8 mm S&W Experimental” is a nothing more than a standard .32 WCF specially loaded for the S&W .32-20 Hand Ejector 1st Model (1899) revolver. It features a solid-head case and a 105 gr metal cased bullet. It was manufactured by UMC for Smith & Wesson in 1900, and its correct factory name is “.32 S&W Winchester Model”. The specimen above is listed here for continuity, but the full range of the 32 – 20 WCF is discussed under Imperial Sporting Rifle cartridges. (Erlmeier, Brandt Ref. 335).
