No flattened primers, no split necks, no bulges observed after firing around 50 rounds, this was the middle of the load ladder and gave the best results for accuracy. Have had the load looked at by someone with more experience than me as well.

exactly. you do not know the actual pressure.

pressure signs and all the other stuff is not a measurement. its merely an indication that you are wayy over pressure IF it happens.

If a grt calculation gives me an accurate prediction of velocity (i.e. velocities line up with actual measurements) I regard the pressure values as correct as well.

Thoughts and ideas of "experienced" people I tend to ignore. Many of these people are lucky firearms are designed with a high factor of safety and tend to not blow up in their faces when they chase the last fps and only rely on the visual appearance of a piece of brass as an indication of pressure...
