Danish vs Norwegian Krag - Action strength/Chamber pressures?

[grueger]

to add on to this thread, has there ever been any empirical test with the pressures for the Krag actions? For the 6.5x55 chamberings I commonly see 40K PSI being touted as the max pressure - which is quite a bit weaker than the max pressure, but I have seen several chambered in 6.5x54 and one in .243 WIN, both of which are loaded much hotter than 40K. I've got a beater rifle that I'd love to mess around with and can't seem to get a clear answer as to what is "safe"; I imagine that will be "it depends".
