Like Johnys Reloading bench might respond....Well, you did not blow your face off. That has to be a good thing. Data does look quite scary to me.
What I mean by that is I am inclined to think your velocity readings were correct or reasonably close. If this is true the data seems to indicate your pressure was on the high side quite early. While I am happy you are coming away safe, I am hoping you are at least a bit nervous about the data.
I had been of the opinion that LVR may be one of the safer propellants you could have worked with, for this loading. As I feel you may be hard pressed to get too much in the case that you may not get yourself in any real trouble. Your data is leaving me second guessing that to a degree to be honest.
My take away is the Pacnor barrel is a fast barrel. I expect your pressure did get on the high side. Photos provided leave a bit to be desired, though I think the far right primers lare looking a bit flat, though I am not noticing any primer flow around the firing pin. suggesting elevated pressure.
Hornady's top load data is often over the top. I expect you will generally need to scale back a grain or more to stay inside of safe pressure limits.
What primer are your reloads primed with?
You will want to evaluate primer pocket growth. Keep those upper end cases separate. Curious what you will see if you were to keep those top loads separate. Deprime the case & seat a new primer. Note, the feel of seating the primers in these cases verses when you initially primed the brass.
Then deprime the lower velocity cases & seat new primers again. are you noticing a difference in seating pressure?
