So, it seems this site is populated with a plethora of metalurgists, ballesticians and other experts. I spent 35 years as a Field Service Engineer, as a front line troubleshooter. So I still ask, why did the pressure change direction? What changed after 10000 firings? Has anyone else noticed the hull case mouth isnt even close to normally opened?
