[QUOTE="Mikecr, post: 1250074, member: 1521"] If best with your load was actually jammed, then you'll need to maintain that, or your pressure peak will drop away from your best. However, an added factor here is that you had bullet bearing seated into donut area. This is not a condition you should have relied on, and the only way to get jam + donut tension back is constant setting back of the barrel. I would start over with new bullet seating depth testing (Berger's recommended). Find a CBTO that would not ever rely on a starting pressure condition. That is, plenty clear of land contact. [/QUOTE]
