I bought a four cavity 35793 mould in 1969. The 3rd Edition of the Lyman Pistol & Revolver Handbook has 9 mm and 357 Magnum loads listed which I use. It also lists 38 Super loads that I don't use. On 02/18/24 I posted here trying to find published 38 Special loads complete with velocity and pressure (V&P) data. A couple of responses/suggestions were received but nothing yet with V&P data.
Lyman technical support was helpful but could not provide 38 Special loads either. The man I spoke with told me the boolet probably dated to the 1950’s and that it had been reintroduced as the 357093/358093 in the 1980’s. One of the responses to my prior post said that the 35793 is based on its big brother, the 429303, which is in the 2002 Lyman catalog. This piqued my interest on the history/origin of the boolet itself.
This morning I asked Lyman if they had an archive of catalogs in an effort to find the oldest one that listed the 35793. Hopefully they have an easily searchable one. I will be at my Virginia house next month. Lots of interesting records have been found during my prior visits to the Library of Congress and the NRA archives. Maybe those sources will work this time. Does anybody out there in booletland have an archive or have any suggestions?
