I checked in QuickLoad to see what it predicts the pressure change might be on .007 with a 135gr bullet in .40SW.
With a max charge of Power Pistol, going from 1.135 to 1.128 made a difference of about 900psi, about the same as 0.1gr powder.
Went from 34,486psi to 35,360psi
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
