You don't know Klem if the advice is correct or not till it is verified. This is only the first step and the reason we call it a load development process.

Nubi,

I am afraid those results defy the principles of chemistry and so at some point we can safely say they are incorrect. The idea you put more powder into a case, expecting it to impart less velocity than a lesser amount of powder is unreasonable.

By all means replicate Dt's loads yourself and let's see the graph. The idea results should be the repeatable is the hallmark of reliability and validity.
