"Here is a 6.5x54 Kurz..."
Dennis, what is the parent cartridge, the Russian round?
Russian? Hardly! It's German -- a shortened version of the 7x57 that was developed in the early 20th century for hunting there. It was designed with a slower twist specifically for shooting 120-130 grain bullets. I generally reform .243 brass; it comes out about x52, but the 2mm short is from the neck, and the neck is plenty long at x52. (To be clear, this case and its development has nothing to do with the Mannlicher-Shoenauer 6.5x54, nor the Husqvarna 6.5x55. The base is, rather, the same size as the 6.5x57, 7x57, 8x57, 9x57, and 9.3x57.)
Interestingly enough, when "Germania Waffenwerk AG Zella-Mehlis" escaped the Russia takeover of East German in 1945 and moved everything they could to West Germany, they re-opened the factory under the family name -- Anschutz.
I honestly don't know how long the action is -- guess I could go check it. But it is certainly a factory-manufactured, original in all ways, 6.5x54 Kurz.
