[QUOTE="Csbc4fun, post: 2927121, member: 114785"] The one shot ladder is to get basic feet per second data and to find pressure signs. Then I select a powder charge from that data and load 30 rounds or more seated at the longest seating depth. I take my press to the range with seating die, clamp it to the bench and seat three, shoot three until I find the best group. That way if I screw up a group I can try it again and at the end not have any rounds seated deeper than I want. [/QUOTE]
