[QUOTE="Mike D Texas, post: 3070013, member: 71221"] I for one like to see videos like this. Many times they will debunk long lived theories. With the improvements in metallurgy, machining, powder, brass and the use of small primer high quality brass, I’m glad to see someone pressing the limits so we don’t have to. They did use a micrometer to measure case head expansion along the way as well. They didn’t get much expansion until way over 60k psi. I want to say they didn’t see anything over the long held .0005” until around 80k. [/QUOTE]
