a) See how many errors you can find in this statement from ~ 2007.
b) Speculate on why those errors were generated.
Myself, I can't help but think it had something to do with what I showed about AA#9 blowing up CZ52s.
"Lynn,
As a result of various technical reasons, the data in the initial print
(year 2000) of the no 2 guide were not tested against a verifiable
standard or protocol.
As a result wrong conclusions and assumptions were made. The result was
that the initial loads were too high.
The recent adjustments were made in two phases i.e.
a) A Reduction in velocity to conform to the correct barrel length since
the initial velocities was for a 9 test barrel.
b) The adjustment of the actual charge weights to conform to the only
Specification/protocol in existence i.e. CIP Commission International
Permanente which is the authority, since this caliber does come from
Europe.
This pressure limit is : <2400bar or 34809Psi.
The final loads as published on the website are thus inline with these
standards.
However, due to the strong design of the CZ 52 pistol, people have been
using ex submachine gun(i.e. PPsh-41) ammunition from the eastern bloc,
which obviously were loaded to a much higher levels, and some of these
will function in the CZ 52 pistol. However, there is ammunition that
will even destroy the CZ 52.
Although the CZ52 gun can handle much higher pressures than some other
weapons it has never been incorporated into an official specification.
The strength of this gun is renowned, which lead to many estimations
of performance and a reputation of being able to handle just about
anything out there on the market.
This is obviously not true and we deemed it necessary to conform to the
official International specifications for the cartridge.
