I am wondering if any of you all can tell me if there are any advantages of using either of these methods if you already have a good shooting load worked up. To clarify this...would it be advised to go back and work up a load using one of these methods even though I already have a good shooting load? From what I have read, the only advantage to either of these methods is to find the sweet spot during a shot cycle. This sweet spot helps just in case your load has a little variance in it. My thoughts about this are...if I weigh and measure every shell I load, what's the advantage of developing a load this way? Thanks in advance.
