I was using this from their site. 115gr Speer HP on the left and lead on the right.What source are you using?
I’m going by the Hodgdon website. It’s always steered me right, and it’s super easy to access.
It’s funny how much information can vary, depending on who is publishing the data.
With my 550, powder charge can vary +- .1 so I pick a middle weight and make that my starting load. As long as it cycles and hits my target, Then doesn’t show any pressure signs, I’m happy. I’m not a bullseye shooter, I just like shooting steel.

I was loading 115gr HAP at 4.2gr and for the 115gr XTPs I carried I was loading at 4.8gr. I also load all of my 9mm to 1.125"

ETA: I also load my 125gr powder coat cast at 4.0gr of win231. Same length. Good for plinking.
