Anyone run this setup over quickload to see what pressure is at the port? I bet it's pretty damn high (regardless of software accuracy.) Early unlock and blowout maybe? Maybe you can gain more dwell with a pigtail tube and let pressure drop a bit more.
QL is useless in this respect, for reasons we have covered before. QL can misrepresent an actual 49,000psi load as 64,000psi. The 49,000psi data will have come from a pressure test breech, whereas QL came from someone generating a software model, never having touched an instrumented breech for that specific case.
