[QUOTE="Mikecr, post: 745000, member: 1521"] In contrast to traditional load development as described; Once you've narrowed powder to seemingly best performance, a move to adjustments in seating afterwards is just gonna mangle what you've done to that point. This, because there is nothing 'fine' about the affects of gross seating adjustments, and if you don't check it gross, well then you really didn't test seating.. Now as your load falls apart with seating adjustments, your judgement about each OAL is poorly influenced. Instead, I pick a mid pressure load with my chosen powder/primer/bullet & follow gross to fine seating testing similar to Berger's recommended. This, because that mid pressure load(down several grains) isn't so near to best as to mask the results of seating adjustments alone. I'm steering clear of any collapse in powder tune. Then I move on to ladder testing with powder, again gross to fine. Aside from neck tension, powder is the finest of adjustments(right down to single kernels). And this is why powder should follow bigger adjustments(like primers & seating), and then you can move on to neck tension last. [/QUOTE]
