Understood, I know they measure by volume dependent on velocity, pressure, powder lot, etc. Make since to do it this way. The printing of the hand load data on the package is to give a good point to mimic the round for the most part.
I did some more checking and the 15 120gr rounds I fired have no ejector marks with slight flattening of the primer but they are all hard to eject. The remaining 5, all of the 140gr rounds, have flattened primers and extractor marks of varying degree. With the exception of the last 2 rounds I fired that had sever extractor and ejector marks and blown primers. I stopped shooting them at this point.
Thank you.
