Hodgdon data for 55gr bullet, 23gr to 25.3gr.
Speer #13 24gr to 26gr.
Sierra #5 23.6gr to 25.7gr for AR type rifles.
23gr to 27.5gr for bolt action rifles
Nosler #6 23gr to 25gr.
As you can see most data hovers around 23gr for a starting load. IMO Hornady data is watered down compared to most other sources. When I have one source(Hornady) that is way low compared to several other sources I through it out, I also through out the one that is way high.
