Interesting results, but to what end??
My understanding is this was a test to see what if any difference was created by using the same load in different brass. It has always been recommended that when changing primers, lots of powder, bullets, or brass one should re-work the load to make sure it is safe. In this test the same everything except the brass itself to see if changing head stamps provided any significant variation.
