You do not get it...I shot those rounds in a Brno ZKK 602 rifle. It has a Mauser lock at least as strong as any M98 actions...the RWS ammunition was dangerously overloaded..
In post #14 you gave the advice not to use RWS ammo or bullets because YOU had a pressure problem in YOUR rifle.
Pressure problems have happened, happen and will happen in the ammunition of every ammunition manufacturer all over this world.
It can happen, even to you, with every american made ammunition also!!!
To be on the save side, my advice was, to use a german made weapon, or a rifle from another CIP country, because they have to withstand an rigid prove test.
Whenever an american rifle is sold to CIP-Country it has to be CIP proved,..... and many of them are simply blown apart...
This is because the american companys are not forced by law to use strong materials.
They tend to use weaker materials, because they are easier to process, cheaper & weaker products are the results.
To compensate this, they load there ammunition on low pressure levels, which results in poor performance.
...These are the hard facts....
Be happy, you had an CIP proved Brno rifle, probably it saved your bacon
