yeah it does look kinda fat but after zooming in there's .020" difference in 200 cases 0.155 - 0.175" I do trim my brass every time I squeeze it and all cases are within a 0.001" using a Giraud trimmer, I'd like to have a single line on the graph but that's just not gonna happenThat really consistent! About the only variation that stands out to me is the starting points of the pressure due to variation in case trim length. And that's not all that much either, as best I can tell???
My point was that annealing and consistent neck prep ( I do not clean my brass.....outside only ) does make difference on paper IMO, every single minute detail does make a difference if you trying to shoot small consistently, some ppl are not willing to go the extra mile, don't have equipment capable or do not think it matters so..... to each their own.
