7x57 factory Dummy made by Kynoch


Some time ago I receive the left specimens from Europe. It has no primer and there is an inscription on his case 7x57 EXERCICE. The right cartridge is shown for comparison

Could it be really factory made Dummy? Is it possible to difine the date of manufacturing of tese cartridges?
Thanks for help


Treshkin - I can’t tell you much about these rounds except to say that Kynoch factory dummies that are nothing more than a bullet and case without primer and pocket are very common in many calibers. I have lots of examples in auto pistol calibers in my own collection. I would say the one with no primer is a factory dummy.


Thank you, John!
