[QUOTE="Deleted member 46119, post: 983243"] I what to publish numbers that I have confidence in. Say I find that the max load produces 2850fps with xxx bullet at yyy COAL, what is that pressure really? So, I'm looking for input on methodology. I could: Make one load of 3 rounds and validate predictions vs actual. Make 1 round from the predicted minimum to maximum and run the series. Validate that against the model. Then run 3 rounds of min and 3 of max to double check. Is that the best or most 'normal' method for producing pressure ladders? [/QUOTE]
