A lot of times that easier said than done. Load data varies from one data source to the next often times it is impossible.
Hodgdon data. 223 Rem, 60gr Hornady V-Max, 2.250 OAL.
Varget Powder, Start=25gr, Max=27.0gr.
Hornady Data. 223 Rem, 60gr Hornady V-Max, 2.250 OAL.
Varget Powder, Start=21.7gr, Max=24.9gr.
It is not uncommon to find a situation like this where the Max charge in one manual is less than the "Start" charge in another. Same bullet, same OAL, same powder, yet completely different results.
As I said, staying within book data is often time difficult if not impossible. Quickload is certainly not perfect, but neither are the loading manuals.
