OK seeing as my last post was to long winded.... let me have another go...
The suggestion is that good brass because it is stronger does not show the signs of pressure in a strong action.
If the failure of brass is the problem that we are trying to avoid, then what does it matter what the pressure is as long as there are no pressure signs?
If the action isn't strong enough, we should be seeing pressure signs in the brass before failure?
So 50K or 70K or even 90K is irrelevent if there is no pressure signs in the brass?
