After about 20 shots above 60k psi just like Mr Elliot says the lever on my Marlin wouldn't click shut indicating that it had deformed. A new lever fixed it.
Clearly the lever/locking block is the week link and like previously said does not inspire confidence. On the other hand it was somewhat reassuring that the lever indicted something was wrong before any catastrophic bolt through face type of failure.
In my experience in dealing with steel and presure for wel over 30 years, rest assured that will not always be the case, thus the MAP of 43,500, but let's not let the facts stand in the way
