Stuck cases in a Cz 52 pistol

[Pattern14]

I purchased several boxes of 7.62 x 25mm a few years ago to use in a Romanian Cz 52 and have been having problems with the cases sticking in the chamber. The headstamp is 22 and the year is 1982. With the barrel removed and the cartridges pushed into the chamber by hand, the rounds are hard to remove and I believe the cartridges may be out of specification. I even had an instance where a live round went into the chamber, failed to fire, and would not eject until I was able to tap the slide back with a small hammer.

When I use a small needle file to chamfer the outside neck edge of the round, I can pull the cartridges out easily. My question is that there must be a better way to resolve the problem. I would hate to have to dump these boxes but I'm not prepared to spend hours filing down individual cartridges.

You can give the rounds a light kiss with a taper crimp die.

I thought of that but don't have a crimp die that will fit without some sort of permanent modification.

Well, you have a 30 Luger or a 30 Mauser set of Dies ? You can always do it the hard way. it's faster than a file but not by much. roll the necks between two steel plates to squeeze the ridge at the mouth down. Don't do it to hard or the bullets will fall out.

I reload 7.62 x 25 with cases i make from .223 brass and have several hundred rounds of Romanian 7.62 x 25 to shoot before i get back to reloading it.



These have too heavy a crip and are rejects

BUT Nobody has addressed the issue of chamber incongruities that might be snagging the ejection

Clean the chamber out real well with various solvents, lacquer thinner, Ed's red, CLP, BreakFree, and use a bore brush in the chamber too! And scrape a nut pick around the chamber and see if you feel a defect.

As a C & R 03, I have had experience with a lotta Milsurps, and chamber issues are real.
