I am a fan of both this pistol and this caliber. One of my favorite combos is my PPSh 41 and my CZ52, both chambered for the 7.62X25 round. But while surplus ammo has been easy to find and very cheap as well, it has been very hard to get a factory JHP and in fact Wolf is currently the only maker. After having this ammo on back order at several places I finally got a couple boxes. My first impression is that like most Wolf it is a small cavity for a hollow point. Looking closer I could see the jacket is scored, that combined with the velocity may allow for expansion. The ammo is brass cased, boxer primed, and non-corrosive. I am going to cheat by not using gel,I will see if it expands in water jugs and wet newsprint. While these are not the preferred test mediums they will serve to see if the bullet will expand.
The water testing was done in 1 gallon milk jugs and the newsprint was completely soaked for 24 hours and was dripping when shot. In other words the newsprint was 100% saturated.
Water proved problematic as I expected it to, most high velocity HPs don't perform well in water, they tend to come apart and that is what happened here. The 1st round completely fragmented with the majority of debris being in the 4th jug. The next round lost it's jacket in the 4th jug and the core was in the 5th. That's 30 inches more or less.
The next two went into soaked newsprint, both went about 8 1/2 inches. Average expansion is .41 which is pretty good for a 30 cal handgun round. A Romanian surplus round completely penetrated 16 inches of wet newsprint and was not recovered. The FMJ, btw, will out penetrate any available military handgun round.
All three cores showed a distinct hexagonal expansion that evidently come from the six score lines on the jacket.
I had zero malfunctions through 40 rounds in the CZ52. It would not feed in the Papashaw however. I think the result in the newsprint as far as expansion will duplicate in gel when I get a chance to test there and I would expect about 14 inches of penetration in the gel but will have to test for that later I hope. I would feel confident is using this ammo for SD/HD. This ammo is reportedly made by Prvi Partizan.
Firearm used: CZ52
Reported velocity: 1640
Penetration: 8 1/2 inches wet newsprint / 30" water
Expansion: .41 |

We should have run the round over the chrono, but it seems all of our electronics have died this year, both timers and chrono.
That said, I have faith in stuff loaded in Serbia--and WSV told me at dinner tonight, that he had found info the ammo was loaded by Prvi for Wolf.
Next summer more testing will be done--with new chrono. |

| Thanks for the report. I have a CZ-52 too, I like it. I'll have to look for this ammunition. |
