[QUOTE="Mikecr, post: 1022460, member: 1521"] I'm glad you're receptive to all these views. There are two reasons I see many tail chasing with development; #1 Seating testing has by far the largest single affect to grouping. Actual seating testing(not tweaking in a seating window) is NOT a fine adjustment. Truth is, powder is the fine adjustment, with only neck tension being lesser. Most have never actually tested seating -to learn this. #2 Unless you know a chosen seating is best, there is no reason for it to be anywhere close to needed. It's just adding an abstract to an already subjective task, and could make powder determinations/interpretations way more difficult. The tail chasing comes in when you find out also that significant seating changes(testing) from your seemingly best powder node cause that node to collapse, which makes it difficult to interpret seating affects(2 changes at once). Jumping into powder with seating settings pulled from your butt is not logical. You're essentially going straight to the fine adjustment before determining proper coarse adjustment. I recommend Berger's seating testing to begin. You can do it with a reduced load while fireforming your brass(which needs to happen before development). Then, with best seating from that, move into incremental powder testing you're confident with. Once you have your powder node(and you already have your coarse seating) tweak seating within a few thou both ways to center the seating node and best shape your groups. [/QUOTE]
