So, it is no wonder that a single-based nitrocellulose powder was soon invented, the all-Italian "Solenite".
The cartridge was then called M91/95 and always retained this name.
Thanks, Brad sight reference/DSCN5461_zpsf99642html"Outside the facts that the fulminate of mercury caused the cases to become so brittle they could not safely be reloaded, that the potassium chlorate caused rust and that the ground glass promoted barrel wear and, in turn, metal fouling, this was a pretty good primer"- Jack O'Connor If the primer on the W. I have other calibers with non W primers in 1915 boxes that the ammo looks original but the box shows the W primer and the picture on the box is supposed to show its contents so they may have been reloaded.
I think you can get it close using the Giles and Shuey book and looking at the head stamp pictures on the boxes.
I happily received a mix bag of .33 WCF factory ammo and some reloads yesterday. is original (no W) I would put it around 1932 to 1946.
Would anyone know the approximate time period for these two headstamps? That’s when the boxes in this caliber no longer show the W primer.
by Alexander Eichener As far as Carcani are concerned, the chicken-and-egg question can be answered clearly: the 6.5x52 cartridge came first, and only then a weapon was tailored around it.
Incidentally, its rimmed predecessor, developed by Italian technicians who heavily drew on Swiss experiments, probably was copied by Ferdinand Ritter von Mannlicher and lateron he presented it to the world as "his" 6.5x53R Romanian and Dutch (the Brits called their Kynoch hunting loads ".256 Mannlicher").
The first cartridge type, called M91 like the rifle, used a hot two-based propellant, Alfred Nobel's Ballistite.
Not only was it erosive and rapidly ruined the rifle's throats, but the Italian state also had to pay royalties to Nobel.
Example: symbol at 12 o´clock | 3 o´clock | 6 o´clock | 9 o´clock The factory code of the state factories are all located at the 12 o´clock position, with the year of manufacture at the 6 o´clock position. As a rule of thumb, this can be said about Russian Federation and Associated States small arms cartridges headstamps: Most East Germany factory numbers begin with 0, examples: 04, 05 Bulgaria used numbers 10 (=Friedrich Engels factory, Arsenal Kazanluk) , 33 (in a double-circle) Hungary used 21 and 23 for example Poland used 21, 54, 234 and 343.
