Nightcrawler,
Yes the CZ52 is fine as far as I know with factory ammo.
All this talk is over some academic strength hierarchy that only matters to a few people.
PCRCCW,
I am not saying that the CZ52 can't take the 40 kpsi of 357 pressures all day.
I am saying that unlike every other pistol I have tested, it can't take the pressure that makes the primer fall out ~65kpsi.
Tell me a load you think a Tokarev can't take, but the brass can. I have a big library of powders and bullets here.
Mike,
try to find some sort of source data. That is engineering talk for the lab notes or raw calculations. I think you will find as I have that there are a dozen books that talk about the CZ52s great strength, based on some assumptions about Czech ammo, that all turns out to be a house of cards. None of the authors can back any of it up with source data.
I got a Letter from Ted Curtis ballistican at Accurate Arms in March of 2000. Ted Curtis, a very old ballistican already was bald and had jowls in his 1966 photo in "Speer 7". All the typos are Ted's:
"7.62 X 25 Tokarev
Due to the large number of handguns imported into the U.S. chambered
for the 7-62 x 25 Tokarev Accurate Arms has developed the following load
data for those shooters who wish to reload the little powerhouse. In
determining the appropriate pressure limit for our load data we tested
various military ammo from China, Russia, Austria Bulgaria and the
Czech Republic. Commercial ammo produced by Sellier and Berloit was also
tested. Based on these tests we arrived at a maximum pressure for our
lad data of 42,000 C.U.P. Only the single lot of Russian ammo was
significantly below this pressure averaging 31,000 C.U.P. The consistent
pressures between all other type sand manufactures was a welcome
surprise . Indeed, the fact that CZech ammo, made for the CZ-52 pistol,
produced the same pressure as that of the other countries was perhaps
the biggest surprise of the whole project. This in spite of the "tribal
lore" regarding this particular handgun and the ammo loaded for it
claiming that shooting Czech ammo in any other firearm so chambered will
causes spontaneous disassembly. The pressure data produced by the ammo
tested certainly doesn't support this theory. ..."
