It would take excessive headspace and brass flow into the neck to have thickened it enough that your original Aztec setting is no longer valid, but it’s not impossible.

Have done this, and interestingly aztec came up with a lower number this time compared to when i originally tested this batch of brass, suggesting its softer now than it was from new & now requires less annealing?
