I will do you one better. What we do here is about "satisfaction" and how well we enjoy what we do. I tumble my brass not because it may affect accuracy, but because I like mine shiny. I load cast and load as consistently as possible, but because I like it that way. If it makes no difference to you, then cast and blast away. Without sarcasm, I wish for great enjoyment for you when you use that process. I appreciate that someone has shown it simple steps how to make MY process more enjoyable.
Yes, others have been segregating by weight. It is not a new concept. This thread is about how to pour more consistent weight boolits. This is first things first. The rest of reloading and shooting follows that.
