[QUOTE="grkldoc, post: 21818, member: 407"] I suppose it depends on you definition of excessive pressures. I have had loads with normal appearing primers, no ejection marks, no or slight sticking which have had pressures in the 70-75K range based on monitoring with a peak strain meter. Yes, it is possible to have excessive pressures and not recognize it with traditional signs. Personally, I believe that if you have signs as above you are already way over acceptable pressure. This is why I have gone to load developement with a chronograph and a peak strain meter. Once I started using the peak strain meter it completely redefined my maximum loads. Measured data is much more useful than guessing. [/QUOTE]
