Thread: What are you using for pressure estimation in your handloads.

Velocity and Gordon’s Reloading Tool (GRT).

I use GRT to predict a load at maximum pressure, and note the velocity. Then run a ladder test up to that velocity. Finally I will calibrate GRT with my measured velocity to correct the pressure value.

If I see any pressure signs something else is wrong. I also cross reference with published data for a sanity check.
