What constitutes a "node" during load developement ?
I understand the desire to get the least velocity variance , but do not know what a node is, or what to look for .
So, you look for the " widest acceptable node/consistent combustion". What would be an indication of consistent combustion, consistent velocity Yes. readings on the chrono ? If you have one you trust. My preferred method is to shoot at 1K and watch my vertical spread Also, how do you determine the width of the acceptable node , is that determined by the variance in powder charge that still yields low extreme spreads in velocity? Right on! I like to have at least 100 FPS acceptable accuracy window
