.44-77 PP bullets.

Jim, for the bushing diameter, for a PP bullet I would start with a bushing inside diameter of about .454. A long lead in of 8 degrees will match the shoulder angle on the 77 case. From there polish it out till you get the fit you want. For a GG bullet go about .010" larger. Polish to a high finish inside and break all sharp edges. I put a nice radius on the outside bottom of the bushing so I can easily tell what end goes down when putting it in the die. Then depending on what material you use you may want to put a nice case harden on the bushing.
