Just a note of warning. Most modern books have very realistic maximum pressure listed since now changing over the to PSI method of measurement. They sometimes aren't at the top of what 'some' brass can stand, but are maximum loads established by the international association called SAAMI.
: It is not a good idea to exceed these posted maximum loads. I've had many rifles that maxed out before I even got to the book maximums, so!
: Please be careful.
: Only European countries (including the UK) have proof testing laws as actually proof test.
