[QUOTE="dougduey, post: 2629358, member: 33159"] 61.8 and 62.2 have virtually the same point of impact, so this is probably your node. I'd load in the middle of this at 62.0gr and do a seating depth test. Do 0.010, 0.020, 0.030 and 0.040" off the lands and see which one it likes the most. If not as tight as you want, pick the best seating depth and do 0.0005 + and - to see which way to go. Most likely you'll be done there. Then run it over a chrono to get your velocity average, ES and SD. This is the OCW method and don't be upset if you don't have single digit ES for that doesn't always equate to small groups. You're looking for a forgiving load that's in a nice node that will give a very repeatable POI [/QUOTE]
