I ran QL, calibrating the case volume against Speer's 125 GDHP bullet at their supposed speeds from their 4" SIG 229 test barrel.
I matched velocties for the 13.1gr load of 1,287fps by using Case Vol =22.5gr(H2O)

Using that same case volume, I the ran a 14.6gr load, which at 1,421fps pretty well matched Speer's predicted 1,437.
Then again, Accurate does max their own load for #9 at 13.0gr...... (?)
