[QUOTE="Mikecr, post: 2061938, member: 1521"] You got it. Full seating testing first. This is a coarse prerequisite for beginning CBTO. Then Powder testing, OCW or ILD/Ladder. Then fine seating tweaking in it's window. This is for tightest group shaping only, and will not collapse your powder load while OTL. Log your final CBTO, and never change it for that bullet and that barrel. Down the road, when your grouping takes a step change, that's the end of your accurate barrel life. Don't chase your tail at this point with a bunch of changes. Instead have a plan to replace the barrel (saves time & money). Given this process order, you can do full seating testing, and primer swapping (another non-tune prereq) during fire forming of new cases. Never move into powder until cases are fully fire formed and stable with your sizing plan. Else you'll be chasing your tail right out of the gates. Add: [I]Barrel life and accurate barrel life are different and independent. [U]Barrel life[/U] is a duration of continued function, and meeting expectations little beyond that (like still 1moa). [U]Accurate barrel life[/U] is a duration of peak results. You first need to find a barrel's potential before you can see it leave.[/I] [/QUOTE]
