The current data is only 12.7 grains. The old data is 16% higher than current print. This is additional evidence to never rely on any single data point for loads.
On a side note, I picked up the most recent Loadbooks. There are a lot of changes there too. The Hornady data above has not yet been corrected.
Noteably, the infamous IMR 800-X with 135 Nosler load is gone.
Good to know sir! (I remember CM mentioning that the new load books had lots of changes...).
10 Ring #1033 - Longslide #1045 - 10mm Loader #1066

Why do I carry a 10mm?
