[QUOTE="dsculley, post: 1029490, member: 77514"] The group sizes alone do not mean anything in this type test. We need to see the targets as well. What you are looking for is a node where the center of 2 or 3 consecutive groups does not move appreciably. This is a "sweet spot". As indicated above, read the entire site on Dan Newberry's OCW test. His examples will help you understand your results. You can also go to [url]www.practicalrifler.fr.yuku[/url] and post your results there. That is a forum maintained by Dan Newberry. He and others who are experienced with the OCW test will help you. Also, as stated above, find your best seating depth then retest. After you find the depth and OCW load, you can retest around that load to verify the results. Some like to shoot a ladder test around the OCW load as well. The downside to the ladder test is that if you throw one shot, it will negate the entire test. If you skip a step in testing for the best load, it just makes it harder and longer. FWIW, Dennis [/QUOTE]
