You know the 7.5 * 45 CZ

You know also the the 7.62 * 45 CZ WHO WAS THE MODEL AFTER
(Rim diam : 11.15 mm; head diam : 11.15 mm, bullet diam : 7.75 mm) .

7.62 * 45 CZ
(Rim diameter : 10.30 mm; head diam: 10.30 mm, bullet diam : 7.72 mm)
Copper washed steel case, tombac bullet

Hi JP,

According to ECRA’s database it’s the prototype Model 1949 of the 7,62x45 Czech, made by Povazske Strojarne. The “normal” model is the Model 1952.

  1. Prototype Model 1949 with a 1946 hstp ?? !!!
    it doesn’t fit.
    What are their source ???

  2. Furthermore the 7.5 ctge is the modele 1950, isn’t it ??
    The CZ made this round in 1946, after they made the Mle 1950 (in 7.5) and after the Mle 1952 (in 7.62)

  3. If you say Mle 1946 I agree, but not Mle 1949.

Jean Pierre,
you are sure, this ammo has a STEEL case?? All my ones have a brass case. They are all reddish from use of acid to clean them, so they all look a bit, like copperplated, but are not. Please check with a magnet the base of the case, so that you not interfere with the inside (steeljacketed) bullet.
Mine have all the same headstamp and comes in 2 variations: LARGE and SMALL primer…
Because, if its really a steel case, i had to add a missing one in my list.
There is also an other experiment between this 2 forunners of the later 7,62x45 M1952. It has a basediameter completelly others at 10,40-42mm and NO HS at all. The neck is also slightly different from all others…
So what I have here is:
1)
Unheadstamped one, 10,40–10,42mm base Pre-runner
2)
headstamped ones with 7,62 in hs (even as bulletdiameter is a real 7,5mm), with an actual bullet diameter of 7,65-7,72mm) headstamp 19 PS 46 7,62, and base diameter of 10,20 -at least mine have that, some even less-
a) with small primer and
b) with large primer
3) than follows the Mod47 7,5x45 with the well known 10,70mm base and various headstamps for the ZG47 rifle
and than comes the Modell 50/52 in 7,62x45 with a 11,15-11,20mm base with a bullet dieametr of 7,82-7,85mm.

The rifle Modell 52/57 has nothing to do anymore with this range, as it was adapted to the AK47 round.
So please let me knew, if yours are really copperwashed steel cases…

All my best
Forensic

Hi Peter !
You are right, they are in fact brass cases (discolored by acid to clean them).
Mines also have either a small primer either a big one.
