[QUOTE="SBruce, post: 522725, member: 21068"] Might try re naming the thread something along the lines of load development pressure signs? Might get more replies.? Just a thought. FWIW, I measure the web of the case, the portion just ahead of the extractor groove with a micrometer. Both before and after firing, and compare the two measurements.........In my experience, when that difference gets over .0003" then the loads are getting warm. When it's .0005" then it's definately warm. The ones I've chrono'd after getting over .0003" expansion have shown velocities of 100 to 300'/sec over what the books say I should be able to get.
