[QUOTE="TRG65, post: 1716957, member: 103919"] I echo the Satterlee testing method to find the velocity nodes. After I find the nodes, I test for seating depths with groups. Then I usually do another group and velocity test a round the best seating depth and velocity node to confirm. My goal is sub .5" average with 3 3-round groups, single digit sd, and 20 for es. The 20 es is usually the one I compromise on as most of my loads are in the low 20s when I work up on a new barrel. This is one of my favorite articles on ES and SD.
