QL gave me a max pressure of 52,745 psi; which is like 99% of spec max. Occurred at 300ms. Muzzle velocity 2809 f/s with a 20" bbl; 2921 w/ 24".
It also shows the "Shot Start [Initiation] Pressure" at 5076, and it's in RED. I'm not sure what that is or how significant it is. That's an Unclenick question.
