Good morning! OK here we go...... take the lowest powder charge of the 3 velocity that are identical in very close to it.how do you know out of each nod which is the more accurate load? and why is the most accurate have to be part of a nod?
Why is that the most accurate, the theories vary, are we controlling the barrel harmonics? Dampening the barrel harmonics? And in return this keeps the muzzle from whipping around and the bullet leaves the barrel in the same plain each shot?
I honestly don't know, but I do know it works.
If you want post your 10 shot card, and I'll help you decipher the data.
