I double checked my Hornady 8th edition this morning for the 139gr I am using, Hornady 139gr Interlock BTSP, and it did say that the start load as 52.7 with max of 62.7. I may want to go a little higher though on my workup, since I'm middle of the road by their manual.
Why are their such differences between using the manual from the manufacture that made the bullet, and say Lyman's? I have both manuals but had decided to go strictly with the manufactures manual since I am using one of their bullets. I also have the Sierra, Speer and Barnes Most recent manuals.
