[QUOTE="dsculley, post: 1597385, member: 77514"] Actually, the OCW method works very well. The "round robin" is designed to spread the shots across the shooting session so that all groups are shot in similar conditions (If you shot a 3 shot group ,then another, then another, changes in winds, lighting and shooter fatigue can affect the result). It is also designed to cancel one of the largest potential downfalls of the ladder test: If you pull a shot and don't realize it this can cause erroneous assumptions in the results. You shoot the OCW at 100 yds to minimize wind effects. When both the Audette Ladder and the OCW are shot correctly they provide the same result: You are looking for an area where the change in powder does not result in a corresponding change in vertical - a flat spot. Dan Newberry, the developer of the OCW method, is an accomplished shooter and is a very good instructor. He as a long range shooting school - Bangsteel.com. His school is well worth the time and money! Trying to combine the two is nothing new. People have tried to adapt these methods so suit their personal whim, sometimes with good results and sometimes not. I personally first test for seating depth using the Berger method. Next, I shoot the OCW test. I then verify the load at range using a small ladder testing a smaller area around the indicated charge. I recently tested my current 6.5x47 load (Developed using the OCW method) by loading two rounds each at 38.5, 38.6 (my go-to load) and 38.7. I shot all six at 287 yds (the longest range available) and all 6 were in a 0.45 moa group (0.38 Vertical). I pulled one shot and it was low and left but it was included in the group measurement. If I had excluded the called flier the other five measured 0.2 moa (0.13 Vertical). This [/QUOTE]
