To answer the question posed by the two "J" guys with another question: What does post by oldman46 have to do with maximum pressure for original Win LW?

To make a further attempt to answer Joe The Westerner's question: It was an exercise pointing out that actual chamber pressures in my present hunting load for my 1908 Win LW are 
easily estimated to be only about 22-23 thousand CPUs and NO ill effects are being seen, at least not yet (ditto for another old ratty early 1900s Win LW in 32-20 used with the original Win HV 80 gr 2000 or so fps HP loads).
Does easily estimated equate with a big pile of WAG, Grisen?
How have you actually verified/confirmed the chamber pressures that you are developing in your two particular low-walls with your particular loads ?

You might also want to take note of the poster in this thread that clearly has been highly and indelibly impressed with Winchester's 1892 lever gun repeater and the original WIN HV "HP" 120 gr loads that Win used to help sell there cute little 1892s. He has been convenced by Winchester's sales propaganda that such loads will DESTROY those little, old 1908 Win LW. I say BS!!
Has your imagination run you over the cliff again, Grisen?    

Now, you might still be lost. Sorry! My apologies to OP if he too is still "at sea". Do you, by any chance, have a technically sound answer to the question asked by OP?
