Re: safe pressure for a Krag

Correction.

On the pressure chart I have, the .405's SAAMI pressure listing has an ^ over it. The ^ means that 44,000psi is the pressure extropolated from loading data in books in the States and that there is no real SAAMI standard listed.

As I understand the CIP and SAAMI standards, is that in Europe, the ammo makers have to load to those pressures, but in the States, SAAMI is merely a suggestion, not an absolute # that must be followed exactly.

This is noted in the text accompanying the pressure chart.

They also noted that the CIP Pezio recordings are taken at the case mouth, which lists a slightly lower (normally) listing than the SAAMI PSI Pezio recordings which are taken on the case body, just up from the head.

I'm certainly not saying the SAAMI suggestions shouldn't be followed, just that I found that an interesting difference in the rules & methods of measuring.

I edited the meaning of ^. My rememberer wasn't quite correct.
