120 class powders

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.

No one said lower velocity was expected, that is a very poor assumption.

So Klem, this is what you are basing your stance on..... Because DT experienced lower velocities at a higher charge weight the test in incorrect? We should all just give up load development based on that conclusion.

Please verify, have you ever, ever developed a load with an extreme spread of ZERO? I seriously doubt it, way too many variables involved. Therefore based your stance regarding the principles of chemistry every developed load with a extreme spread of 1 or greater is also incorrect.

With respect, this advice is based on the premise your initial findings are correct - unfortunately they are not.

Again I stand on my advice to DT based on the facts he shared, .4 grains difference with 11fps spread would be where I would investigate in greater detail to verify if it was a node or not.
