Lew et al - I have never been able to find any really comprehensive reports on the entire SSB project. There is some information on one loading in “Colt’s Model 1971 Double Action Pistol,” a Colt Industries document of 17 pages, unknown publishing date but probably c.1971. There is also an addendum dated 11/17/67 to the “Salvo -Squeezebore System - Critique” of simply three pages, but it applies only to the .50/.30 project as far as I can see. Another Colt Industries Document, dated January 19, 1972, “Trip Report DC Week, January 10,” has some results on testing from H. p. White Lab (negative). It is scant, however. A thesis by John-Paul Shebalin, probably never published, titled “Tapered Bore Guns and Ammunition,” has some more information, but since it covers other taper-bore subjects, it is not comprehensive by any means, although over-all, a well-researched paper and well done. There is also a two-page paper by Russell Robinson. Bill Woodin must have known him (perhaps still does - don’t know if Mr. Robinson is still with us or not) as he lived in Tucson, and invented the SSB in 1948. The paper is undated and there is no indication of the publication, if any, that it it taken from.
I sent a lot of this material to Frank Hackley, so there will be some coverage of the program in HWS III when it is finished.
To make a long story short, it is doubtful, just as Lew says, that we will ever find real testing information or even in-house identification desginations for all of the various SSB loads in 9mm, or in the other calibers, for that matter.
I have found nothing on the matter of the SSB 9 mm rounds for Israel and thier program with the Uzi and SSB, although I have two variations of the cartridge. It seems the hardware is easier, in this case, to come by than is comprehensive information on the project. I suspect Colt would have kept good records. Their reports on various in-house development programs that I have seen have been quite thorough. However, the chance of getting that infromation, I think, is from zero to none.
