[QUOTE="JD Jones, post: 2602009, member: 120849"] 58.5 grain was the charge weight. I did 4 groups starting at 20 thou off. Those were 40 and 50 respectively. I split that down the middle for the OCW I did a ladder test at 200 yards at 20 thou off before the seating depth test. I landed on 58.5 because the vertical dispersion I interpreted from the target between 58 and 59 See above: I did a ladder test first. The way I interpreted the test 58.5 seemed a middle point between two loads showing the least vertical dispersion. I’ll admit tho the test was only at 200 and I was trying my best to move forward vs starting at a greater distance to show the results in dispersion at the various charges. That’s how I landed on doing the OCW… I don’t have a distance range I can drive to without a larger commitment to the day [/QUOTE]
