HAHA I know you have been chomping at the bit to see someone mess with the manual settings. From what I can tell from my tests with the 190gr we are at the top end of the bore/caliber/fill pressure performance curve. For example the discharge setting dumps 250psi but the velocity comes down. I think the only way to get more would be to change the fill pressure to 3600-4000psi. What I did gain was accuracy with that bullet. It went from good groups to great groups.
