. . . all the current latest reloading information is in PSI now. The way pressures are tested has changed to check out the overall "burn progress" as opposed to a single point check as done by the old "crusher" process.

There is no "conversion factor" between CUP and PSI.

Gotta remember . . . Elmer blew up a lotta guns.
