[QUOTE="Mikecr, post: 972410, member: 1521"] I fully agree with benchracer. Found the same things in similar ways. I do Berger's test during initial fireforming of brass, at ~2% under book max(conservative). Once cases are stable I move to ladder testing with the best of my seating. Believe me, ladders look different with good seated depth -vs- bad. I usually take charges to 'MyMax' as measured at the weblines during the ladder. Then, when I'm confident in chosen powder charge, I tweak seating a smidge both ways to shape grouping. That is, if the load is a keeper(won't always be). If the load sucks, and I really really want it anyway, then it gets ugly. My only adjustments left are primers, primer striking, or new barrel. Not a solid plan here yet... Flash holes, primers, and their striking affect ES. You can change triggers & see it. And of course a new barrel is scorched Earth. But I'm not so picky on load components. I usually just pull out different bullets, same seating, and re-run a ladder. See if that twirls my propeller.. [/QUOTE]
