40-65: Learning what I can

[SgtDog0311]

Kurt, help me decipher here. On the PRG Browning that is posted above what do the "two" numbers indicate where the transition is identified (12*-45-0)? Looks like it would be a 12* or a 45* but not both. The Win just shows a 45* and that's all. This is my first exposure to reamer diagrams. Gonna go shoot some but I'll check back in when I return. Thanks, John
